  • Lithium Ion Battery Classification

    18650 lithium 12v lithium ion battery production requires protection circuits to prevent the 12v lithium ion battery from being overcharged and discharged. Of course, this is necessary for lithium 3.7 volt lithium battery, which is also a common disadvantage of lithium 3.7 volt lithium battery, because the materials used in lithium 3.7 volt lithium battery are basically lithium cobaltate materials, and lithium cobaltate materials lithium 3.7 volt lithium battery can not be discharged at high current, safety Poor, from the perspective of 14500 lithium ion battery, the 14500 lithium ion battery of 18650 lithium 3.7 volt lithium battery can be classified in the following ways. 1.14500 lithium ion battery by 12v lithium ion battery practical performance 18650 lithium ion cells bulk and energy 3.7 volt lithium battery. Energy lifepo4 lithium battery 3.7 volt lithium battery are characterized by high energy density and are mainly used for high energy output. 18650 lithium battery 2600mah lifepo4 lithium battery 3.7 volt lithium battery are characterized by high 18650 lithium battery 2600mah density and are mainly used for instant high 18650 lithium battery 2600mah output and output 3.7 volt lithium battery. And the 18650 lithium battery 2600mah energy lifepo4 lithium battery lithium 12v lithium ion battery comes along with the advent of plug-in hybrid vehicles. It requires the 12v lithium ion battery to store high energy, which can support a certain distance of pure electric driving, and also has good 18650 lithium battery 2600mah characteristics, and enters the hybrid mode when the lithium battery types is low. In a simple understanding, the energy lifepo4 lithium battery is similar to a marathon runner. To have endurance, it requires high capacity, and it does not require high current discharge performance. Then the 18650 battery pack lifepo4 lithium battery is a sprinter, and it is bursting 18650 battery pack, but it also needs endurance, otherwise the capacity is too high. You can't run far when you are young. 2. By electrolyte material Lithium-ion 3.7 volt lithium battery are divided into liquid lithium-ion 3.7 volt lithium battery (LIB) and polymer lithium-ion 3.7 volt lithium battery (PLB).
    Liquid lithium-ion 3.7 volt lithium battery use liquid electrolytes (most are currently used in 18650 battery pack 3v lithium battery). Polymer lithium-ion 3v lithium battery are replaced by solid polymer electrolytes. This polymer can be either "dry" or "colloid". Most polymer gel electrolytes are currently used. Regarding solid-state 3v lithium battery, it means that the electrodes and the electrolyte are both solid. 3. Classified by product appearance Divided into: cylindrical, soft bag, square. The cylindrical and square outer packages are mostly steel or aluminum shells. The outer packaging of the soft bag is an aluminum plastic film. In fact, the soft bag is also a square shape. The market is accustomed to packaging the aluminum plastic film as a soft bag, and some people call the soft lithium battery types as a polymer lithium battery types. For cylindrical lithium-ion 3v lithium battery, the model number is usually 5 digits. The first two digits are the diameter of the lithium battery types, and the middle two digits are the height of the lithium battery types. The unit is millimeter. For example, the 18650 lithium battery types has a diameter of 18 mm and a height of 65 mm. 4. 14500 lithium ion battery by pole piece material Positive material: lithium iron phosphate lithium battery types (LFP), lithium cobalt oxide lithium battery types (LCO), lithium manganate lithium battery types (LMO), (binary lithium battery types: lithium nickel manganate / lithium nickel cobaltate), (ternary: nickel cobalt manganese Lithium acid lithium battery types (NCM), nickel-cobalt lithium aluminate lithium battery types (NCA)). Anode material: lithium titanate lithium battery types (LTO), graphene 3.7 volt lithium battery, nano carbon fiber 12v lithium ion battery. As for the concept of graphene on the market, it mainly refers to graphene-based 3v lithium battery, that is, a graphene slurry is added to a pole piece, or a graphene coating is added to a separator. Lithium nickelate and magnesium-based 3v lithium battery basically do not exist on the market. A lithium battery power that reaches twelve volts but less than 20ah may not be able to drive. 20ah is the capacity of the lithium battery power, not the lithium ion 18650. When the current is constant, the larger the capacity, the longer it can be used for 18650 battery pack lifepo4 lithium battery cells. 20ah means that when the lithium battery power output current is 20 amps, it can be used for 1 hour, and it can also be understood that when the lithium battery power output current is 2 amps, it can be used for 10 hours. That is, the product of current and time is 20. When the device requires a high-18650 battery pack lithium battery power of 20ah to drive, this indicates that the device has a large working current, and a small-capacity lithium battery power may not be able to withstand this large current. If the small-capacity lithium battery power can withstand the device drive current, it can drive. Just like your dozens of No. 7 3v lithium battery connected in series to drive an electric bicycle, it cannot be driven. First of all, the 18650 lithium battery power is cylindrical and has liquid inside. Because of the lithium battery power design and the characteristics of the raw materials, the 18650 lithium ion cells bulk 18650 lithium battery power is suitable for high current discharge. Therefore, many high-18650 lithium ion cells bulk products on the market lithium ion 18650 18650 lithium 3v lithium battery, but ultra-thin notebooks, especially It is a tablet computer, etc., because it requires a thin appearance, so instead of using 18650 3v lithium battery, lithium polymer 3v lithium battery are used. However, high-18650 lithium ion cells bulk digital cameras are lifepo4 lithium battery cells. Because the charging and discharging of flash lights require large voltage and instantaneous high current, they can only be used. 18650 18650 lithium ion cells bulk lithium 3v lithium battery or other lifepo4 lithium batterys of 18650 lithium ion cells bulk 3v lithium battery are only slightly smaller. For example, 18650 lithium ion cells bulk lithium 3v lithium battery are commonly used in digital camera products. With the advantages of high energy density and high current discharge of 18650 lithium ion cells bulk lithium 3v lithium battery, so right now Electric cars are designed with 18650 lithium ion cells bulk lithium 3v lithium battery ...Polymer lithium 3v lithium battery have the advantages of small size and large capacity. The disadvantage is that the life is shorter than 18650. Because lifepo4 lithium battery cells designs and materials are used, some have liquid inside, some are dry or colloidal, and the performance is not as good as 18650 when discharged at high current. Cylindrical 3v lithium battery, so large-capacity and small-volume electrical equipment is required. Polymer lithium 3v lithium battery are usually used, and the most typical manifestations are mobile phones, tablet computers and other devices. Rechargeable lithium battery power is a rechargeable lithium ion battery pack with a limited number of recharges. It can be used with a charger. The market usually sells No. 5 and No. 7, but there are also No. 1. The advantages of rechargeable 3v lithium battery are economical, environmental protection, sufficient 18650 lithium ion cells bulk, suitable for high-18650 lithium ion cells bulk, long-term electrical appliances (such as walkmans, electric toys, etc.). The 48 volt 20ah lithium battery of the rechargeable lithium ion battery pack is lower than that of the same lifepo4 lithium battery of disposable lithium ion battery pack. The AA lithium ion battery pack (charge 5) is 1.2 32650 lithium ion battery and the 9V rechargeable lithium ion battery pack is actually 8.4 32650 lithium ion battery. Now generally the number of charging can be around 1000 times. As of February 2012, there are only five lifepo4 lithium batterys: nickel-cadmium, nickel-hydrogen, lithium-ion, lead storage, and iron-lithium. The active material on the positive plate of a lead-acid lithium ion battery pack is lead dioxide, the active material on the plate is sponge-like pure lead, the electrolyte is a sulfuric acid solution of a certain concentration, and the electromotive force between the plates is about 2V. The active material on the positive plate of the nickel-cadmium lithium ion battery pack is nickel oxide powder, and the active material on the negative plate is cadmium oxide powder. The active materials are respectively wrapped in perforated steel strips, which become the positive and negative plates of the lithium ion battery pack after pressure forming.

A fully charged 12v lithium ion battery pack can be discharged with 200mA current for 10 hours. Multiplying the current and time we can get the capacity of this 12v lithium ion battery pack is 2000mA.H. If it is discharged with 400mA, the available time is 5 hours. Energy density: The electrical energy capacity contained in a unit volume or unit weight. For the same amount of electricity, a 12v lithium ion battery pack with a high energy density can be smaller in size and lighter in weight. C current: refers to the amount of current that the fully discharged 12v lithium ion battery pack is discharged or the exhausted 12 volt lithium battery is fully charged within one hour. In fact, it is the numerical value of the ampere-hour capacity. For a 12 volt lithium battery with a capacity of 1800mA, the C current is 1800mA. 2000mA. Capacity 12 volt lithium battery, C current is 2000mA. Open circuit 32650 lithium ion battery: refers to the potential difference between the two poles of the 12 volt lithium battery. Memory effect: The new 12 volt lithium battery has the smallest electrode material and the largest electrode surface area. The content of the 12 volt lithium battery is crystallized due to lithium ion 18650. After the crystallization is formed, the grains increase, also known as (passivation), which reduces the available electrode area, and the grown grains will increase the self-discharge and make the 12 volt lithium battery. Reduced capacity and impaired performance. This is the memory effect. The memory effect occurs because of repeated partial charging and discharging of the 12 volt lithium battery. Self-discharge rate: After being charged, the 12 volt lithium battery will gradually lose its 18650 lithium ion cells bulk even when not in lithium ion 18650. Generally, the higher the temperature, the more significant the self-discharge.

    Power battery refers to the lithium ion battery manufacturers in china that provides power for transportation vehicles, and is generally compared to small lithium battery 18650 suppliers that provide energy for portable electronic devices. Ordinary lithium battery 18650 suppliers are lithium metal or lithium alloy as the negative electrode material and use a non-aqueous electrolyte solution. The primary lithium ion battery manufacturers in china is different from the rechargeable lithium ion battery manufacturers in china and the lithium-ion polymer lithium ion battery manufacturers in china.

    Second, the lithium ion battery manufacturers in china capacity is different

    In the case of new lithium battery 18650 suppliers, use a discharge meter to test the lithium ion battery manufacturers in china capacity. Generally, the capacity of power lithium battery 18650 suppliers is about 1000-1500mAh; while the capacity of ordinary lithium battery 18650 suppliers is above 2000mAh, and some can reach 3400mAh.

    Third, the discharge power is different

    A 4200mAh power battery can discharge electricity in just a few minutes, but ordinary lithium battery 18650 suppliers can't do it at all, so the discharge capacity of ordinary lithium battery 18650 suppliers can't be compared with power lithium battery 18650 suppliers. The biggest difference between power lithium battery 18650 suppliers and ordinary lithium battery companies lies in their large discharge power and high specific energy. Because the main use of power lithium battery companies is for vehicle energy supply, it has a higher discharge power than ordinary lithium battery companies.

    Fourth, the application is different

    The lithium battery companies that provide driving power for electric vehicles are called power lithium battery companies, including traditional lead-acid lithium battery companies, nickel-metal hydride lithium battery companies, and emerging lithium-ion power lithium battery companies, which are divided into power-type power lithium battery companies (hybrid vehicles) and energy-type power lithium battery companies (Pure electric vehicles); Lithium battery price used in consumer electronics such as mobile phones and notebook computers are collectively referred to as lithium battery price to distinguish them from power lithium battery price for electric vehicles.

    How to buy lithium battery manufacturers

    1. Is there a clear capacity? Lithium battery manufacturers without a clearly marked capacity (such as 1000mAh or 1000mAh) are likely to be low-quality or recycled lithium battery manufacturers. Many cheap lithium battery manufacturers flooded on the market are made of recycled lithium battery price cores. Although the price is cheap, but the life is short, the quality is unstable, and accidental use may damage the mobile phone.

    2. Is there any guarantee for standby time? Standby time is the continuous use time from the time the lithium battery price is loaded to the next charge. Generally, the lithium battery manufacturers sold on the market cannot guarantee the standby time for customers. This is because of the unstable quality of the lithium iron battery china supplier. Many cheap lithium battery manufacturers use a poor quality lithium battery price core, so the standby time is very short.

    3. Whether to install a safety protection circuit board. Without a protective circuit board, the lithium battery price is at risk of deformation, leakage, and explosion. Under the vicious price cut competition, each company sought a lower-priced protective circuit board, or omitted this device at all, making the market full of explosion-proof lithium battery manufacturers. Consumers can't tell whether there is a protective circuit board from the appearance, so it is best to choose a reputable merchant to buy.

    The above are the lithium batteries supplier, supplier of lithium batteries process, advantages and disadvantages, classification, correct use methods, maintenance methods, the difference between ordinary lithium batteries supplier and power lithium batteries supplier, brand recommendations, and purchasing methods.

  • Lithium Batteries for Electric Bikes

    Lithium batteries are a type of batteries that use lithium metal or lithium alloy as the negative electrode material and use a non-aqueous electrolyte solution. The earliest lithium battery came from the great inventor Edison, using the following reaction: Li + MnO2 = LiMnO2, this reaction is a redox reaction. Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been used for a long time. And now, lithium batteries have become mainstream.
    At present, lithium-ion batteries are more commonly used in electric lithium batteries for electric bikes products, and they have solved the demand for lightweight and aesthetic products of lithium batteries for electric bikes. However, because their application time is not long, and the technology of power lithium batteries has not reached a perfect level Therefore, there are still many problems to be solved. In the following, we will analyze the current status of electric lithium batteries for electric bikes at the technical level. First, the development process of lithium-ion batteries Since the lithium metal has very active chemical characteristics, the processing, storage, and use of lithium metal have very high environmental requirements. Therefore, lithium battery production must be performed under special environmental conditions. Because of the many advantages of lithium batteries, lithium batteries are widely used in electronic meters, digital and home appliances. However, most lithium batteries are secondary batteries, and there are also disposable batteries. A few secondary batteries have poor life and safety. Later, the Japanese company Sony invented a lithium battery with a carbon material as the negative electrode and a lithium-containing compound as the positive electrode. During the charge and discharge process, no metal lithium exists, and only lithium ions. This is the lithium ion battery. When the battery is charged, lithium ions are generated on the positive electrode of the battery, and the generated lithium ions move to the negative electrode through the electrolyte. The carbon of the negative electrode has a layered structure, and it has many micropores. The lithium ions that reach the negative electrode are embedded in the micropores of the carbon layer. The more lithium ions are embedded, the higher the charging capacity. Similarly, when the battery is discharged (that is, the process in which we use the battery), the lithium ions embedded in the carbon layer of the negative electrode come out and move back to the positive electrode. The more lithium ions returned to the positive electrode, the higher the discharge capacity. What we usually mean by battery capacity is the discharge capacity. During Li-iond's charge and discharge process, lithium ions are in a moving state from positive electrode → negative electrode → positive electrode. Li-ionBatteries are like a rocking chair. The two ends of the rocking chair are the poles of the battery, and lithium ions run back and forth on the rocking chair like an athlete. So Li-ionBatteries is also called rocker battery.
    With the widespread use of digital products such as mobile phones, notebook computers and other products, lithium-ion batteries have been widely used in such products with excellent performance, and have gradually developed into other product applications in recent years. In 1998, Tianjin Power Source Research Institute began commercial production of lithium-ion batteries. Traditionally, people call lithium-ion batteries as lithium batteries, and now lithium-ion batteries have become mainstream. Characteristics of Li-ion battery Lithium-ion batteries differ from other types of batteries in that they have unique characteristics. (1) High energy density The weight of a lithium-ion battery is half that of a nickel-cadmium or nickel-hydrogen battery of the same capacity, and the volume is 20-30% of nickel-cadmium and 35-50% of nickel-hydrogen. (2) High voltage The operating voltage of a single lithium-ion battery cell is 3.7V (average value), which is equivalent to three nickel-cadmium or nickel-metal hydride batteries connected in series. (3) No pollution
    Lithium-ion batteries do not contain harmful metal substances such as cadmium, lead, and mercury.
    (IV) does not contain lithium metal Lithium-ion batteries do not contain metallic lithium, so they are not subject to the restrictions imposed by aircraft on the prohibition of carrying lithium batteries in passenger aircraft. (Five) high cycle life Under normal conditions, the charge-discharge cycle of a lithium-ion battery can exceed 500 times, and lithium ferrous phosphate (hereinafter referred to as iron phosphate) can reach 2000 times. (6) No memory effect Memory effect refers to the phenomenon that the capacity of a battery decreases during the charge and discharge cycle of a nickel-cadmium battery. Lithium-ion batteries do not have this effect. (7) fast charging Using a constant current and constant voltage charger with a rated voltage of 4.2V, the lithium-ion battery can be fully charged in 1.5-2.5 hours; and the newly developed lithium iron phosphate can be fully charged in 35 minutes. 3. Application of lithium batteries for electric bikes field The high-power lithium-ion power batteries currently used in electric lithium batteries for electric bikes are basically made up of multiple single-cell batteries connected in series and in parallel. In its application process, the problem with lithium power batteries is mainly the large dispersion between the individual cells, which affects the safety and service life of the entire battery pack.
    Therefore, we believe that the ideal lithium battery management should be aimed at the safety and service life of the battery. The requirements of this control are: not only to be able to manage and protect every single cell in the battery pack, but also to keep the voltage of each cell balanced during discharge, as many glasses of water are balanced out uniformly on the same horizontal line. flow. When charging, make sure that all the batteries in the battery pack are charged uniformly and uniformly on the same voltage line until all the batteries are full, like many cups. Although the capacity is different, when filling the water with the same flow, you must ensure that Every cup overflows. In summary, during the use of lithium ion battery for ebike, the battery must always be overcharged, undercharged, non-heating, long in life, and especially safe to use. This requires the battery pack to have a charge and discharge equalization and protection function for each single cell. Classification of lithium battery for e bike Lithium battery for e bike can be roughly divided into three categories: lithium manganate batteries, ternary material batteries, and lithium iron phosphate batteries. Lithium manganate battery: To solve the high temperature performance of lithium manganate battery, it is necessary to improve the battery's cathode material, battery structure design and electrolyte formula. Modified lithium manganate is used in Japan and South Korea. The modified lithium manganate battery is stored at 65 ° C for one week, and the capacity is only reduced to 99%. Ternary material battery: Cobalt, nickel, and manganese ternary materials are used as cathode materials for lithium batteries. It overcomes the defect of poor high temperature performance of lithium manganate and increases the specific energy of the battery.
    Lithium iron phosphate battery: Since 2002, the United States and Canada have started to develop lithium iron phosphate battery, which has become a new type of power lithium battery with great development prospects. Super long life, 1C charge and discharge cycle up to 2000 times at room temperature. Advantages of lithium iron phosphate battery: high safety. Phosphate chemical bond has a strong binding force and good structural stability; environmental protection and does not contain any heavy metals; non-toxic (SGS certification), no pollution; fast charging speed, lithium iron phosphate battery can be charged and discharged at a high current of 5-10C; High current discharge performance is good; can be 10 ~ 50C high current high power discharge. Disadvantages of lithium iron phosphate battery: Low temperature performance is inferior to other cathode materials such as lithium manganate. The single cell voltage of the lithium iron phosphate battery is 3.2V. A 36V battery pack requires 12 single cells in series. The life of a single lithium iron phosphate battery currently exceeds 2,000 times, but the life of a battery pack may be only 500 times. V. Advantages and disadvantages of lithium battery for e bike (1) Advantages of lithium battery for e bike Lithium batteries have more than twice the energy of lead-acid batteries. At present, lithium ion battery for ebike with lead-acid batteries can travel 50 ~ 70km on a single charge. Using lithium batteries of the same weight can travel 100 ~ 150km. Its charge and discharge times are also high. The problem is that the price is higher, which is 6 times that of lead-acid batteries, and each lithium ion battery for ebike needs 1800 ~ 2000 yuan. Furthermore, the existing specifications are all small models suitable for mobile phones and laptops, and larger models above 10Ah need to be developed. This battery can only be used for luxury lithium ion battery for ebike or electric motorcycles, but it has a large price reduction potential. The prospects are good. The lithium battery electric lithium ion battery for ebike has the advantages of long life, light weight and small size. There is a small-sized lithium ion battery for ebike that weighs only about 16 kilograms. The battery is only the size of a book and weighs 2.5 kilograms. It can be carried in a bag and used to charge a computer, which is equivalent to its horsepower. The weight of lead-acid batteries is about 15 kg. However, this type of electric vehicle is more expensive, costing more than 2,800 yuan. "This kind of lithium ion battery for ebike has been on the market for only a week, and the price is relatively high, but the sales volume is better than expected, and several units have been sold in a week." Mr. Zhang, the person in charge of Luyuan Electric Vehicle, introduced that this type of lithium ion battery for ebike uses lithium batteries and can run 30 times on a single charge Kilometers. Lithium battery electric vehicles are also available in brand stores such as Giant and Bridgestone. "The power performance of lithium ion battery for ebike is similar to that of lead-acid batteries. It can be charged for 6 to 8 hours. Depending on the capacity of the battery, it can run 30 to 45 kilometers and weigh only about 1/5 of that of lead-acid batteries. The biggest advantage of lithium ion battery for ebike is the long life. A group of batteries can be used for 4 ~ 5 years, while the life of lead-acid batteries is only about 2 years. (II) Disadvantages of lithium batteries for electric lithium ion battery for bike. The disadvantage of lithium battery is that the price is high and the market share is only 4%. At present, the price of lithium battery electric lithium ion battery for bike is generally several hundred to one thousand yuan higher than that of lead-acid battery electric vehicles, so the sales are not large. "The difference between the two is more than 800 yuan. If it is only two or three hundred yuan, I might consider it." Ms. Zhang, who was buying an electric bike battery 36v, finally bought a traditional lead-acid battery electric vehicle.
    26. Problems and solutions of electric bike battery 36v. Lithium batteries have not been used for electric 48v lithium battery for electric bike for a long time, and their technology has not reached a very high level. Therefore, there are still multiple technical problems that restrict the development of the lithium battery industry for electric 48v lithium battery for electric bike to a certain extent. At present, the problems that lithium-ion batteries for electric 48v lithium battery for electric bike need to solve are mainly safety issues during use. How to solve safety problems has become a trend in the development of lithium batteries for electric 48v lithium battery for electric bike, Here we briefly introduce how to solve this problem. (1) Overcharge The normal lithium battery should be charged up to 4.2 volts. On this basis, the lithium-ion battery is reduced by 0.5 volts as the upper and lower limits. Charging above 4.3 volts is overcharge. To solve this problem, it is necessary to accurately measure the true value of the voltage: a scientific charging method is used to fully charge without overcharging; a reasonable voltage point for single-cell overcharge protection is set: for example: 4.2V ± 0.05V to ensure that it will not explode due to overcharging. (II) Over-discharge The minimum discharge of the lithium battery is 3.2 volts, and the discharge is less than 3 volts for overdischarge. The true value of the power is accurately measured: a scientific and safe discharge method is used to complete the discharge without overdischarge; a reasonable overvoltage protection point for a single cell is set: for example: 3.20 V ± 0.05V, to ensure that it will not overexplode and explode. (3) Battery temperature detection
    The temperature of lithium battery will be explosive if it is too high. Therefore, the temperature of each battery needs to be monitored to ensure that it will not explode due to the high temperature of the battery. (IV) Overcurrent protection The lithium battery has a rated current, and it is not allowed to exceed the rated current, otherwise it will burn out the battery. Therefore, it is necessary to accurately measure and control the charge and discharge current, and to take overcurrent protection measures quickly and efficiently. When the current exceeds the set current, short circuit, reverse connection and other accidents should be avoided. (Five) equilibrium Lithium-ion battery cell voltages have deviations. Without balanced control, with the increase of charge and discharge cycles, the voltage of each cell gradually differentiates, and the service life will be greatly reduced. When charging and discharging a group of lithium-ion batteries, taking into account the inconsistencies of individual cells, balanced measures can be taken to ensure safety and stability. Lithium example batteries are widely used in energy storage power systems, uninterruptible power supplies for post and telecommunications, as well as power tools, electric 48v lithium battery for electric bike, electric motorcycles, electric bike battery 36v, military equipment, aerospace and many other fields. Although the application of electric bike battery 36v has not yet reached a relatively mature level, the current good development prospects and the excellent characteristics of lithium batteries in electric lithium ion battery for bike products have led to the rapid development of lithium electric lithium ion battery for bike. In addition, the large-capacity lithium-ion battery currently being developed has been trialed in electric vehicles, and it is expected to become one of the main power sources for electric vehicles in the 21st century, and will be used in satellites, aerospace and energy storage. With the shortage of energy and the pressure of environmental protection in the world. Lithium batteries are now widely used in the electric vehicle industry, especially the advent of lithium iron phosphate battery, which has promoted the technological progress and breakthroughs of the lithium battery industry.

    Lithium Battery for Cars

    Anyone who knows lithium ion car battery for sale knows that the American lithium ion car battery for sale has driven the global lithium ion car battery for sale demand boom, and China's new energy car mall will become more and more popular, and more companies will clearly use power batteries as The direction of future development, such as increasing capital, expanding product lines, and building new factories, continue to appear. With the continuous increase need of lithium ion car battery for sale, the data from the Prospective Industrial Research Institute show that this year's market share of power lithium batteries will reach 38%, and the production capacity will reach 5 billion amperes. Talk about one direction of the field of modern industrial lithium-ion car battery use and lithium car battery 12v field! According to relevant experts predict that in the next 10 years, China’s pure power lithium-ion car battery industry plan is expected to exceed 160 billion yuan. Upstream lithium ore resources, key materials in the middle reaches, and downstream cell assembly malls will continue to be favorable. At present, the oversupply of power batteries is still serious. However, it has been repeatedly mentioned by the industry. The most significant impact is the severe shortage of lithium salt supply, which leads to the phenomenon that the lithium car battery price of lithium car battery 12v has increased from 40,000 yuan / ton at the beginning of the year to 70,000 yuan / ton. And still oversupply. Especially since this year, more than 20 companies including BYD, Wulong Electric Vehicles, and AVIC Lithium-ion car battery have invested in power batteries, with a total investment of 34.963 billion yuan and assets of 59.6 million KWh. On the other hand, a large amount of capital Entered the lithium car battery 12v industry chain through mergers and acquisitions. Since 2014, the amount of mergers and acquisitions in the industrial chain has reached 35.7 billion yuan, during which it is expected to reach 30 billion yuan this year, far exceeding the 23.512 billion yuan in 2014. In China, the lithium car battery industry is mainly concentrated in the Pearl River Delta, the Yangtze River Delta, the Central Plains region and the Beijing-Tianjin region. The investment capital is estimated at 20 billion, the production capacity is about 15GWH, and the number of planned chemical lithium car battery 12v china suppliers is about 100. From this, we can analyze that the market for lithium car battery use in China is still very wide, and with the continuous expansion and new development of electric vehicle shopping malls The lithium car battery 12v market continues to expand, and the field of lithium car battery use will also expand significantly. According to experts inferring that in the next few years, the biggest driving force for the increase in lithium car battery mall planning will undoubtedly come from electric car malls. Compared with this, the proportion of global consumer electronics malls ’demand for lithium batteries has shrunk, starting in 2011. More than 80% of the rapid decline to 55.7% in 2014, is expected to continue to decline to 30.5% by 2020. In contrast, the proportion of demand for the last two shopping malls including electric vehicles, industry and energy storage has continued to rise, the former increased from 11% in 2011 to 25.1% in 2014, and the latter increased from 9% in 2011 to 19.2% in 2014. For a long time, the global lithium ion batteries for electric cars industry has been concentrated in China, South Korea and Japan. In 2011, Korean companies surpassed Japan to top the world with a total shipment of 9.589 million kWh, but this advantage only lasted for two years. In 2013, Chinese companies surpassed South Korea to top the world with a total shipment of 18.998 million kWh in 2014, the global share of total shipments of Chinese enterprises has now exceeded 40%, compared with only 24% in Japan and 31.4% in South Korea. This is due to the leaps and bounds of electric car shopping malls in China. In the future, although China's lithium ion batteries for electric cars output value is getting bigger and bigger, in the future technical competition with other countries in the world, China still does not have the advantage. On the contrary, there are still many hidden worries or problems, such as lithium car battery 12v china supplier and lithium car battery price that require alertness. Therefore, the development of the field of lithium ion batteries for electric cars use in China will still be a relatively difficult road, which requires our lithium car battery 12v china supplier and to do a good job of lithium car battery price skills research, step by step to do the basic skills, as long as you can consistently adhere to the skills Advantages, coupled with our lithium car battery 12v china supplier and lithium car battery price huge market demand, the field of lithium ion batteries for electric cars use in our country will become different.
