Lithium-ion batteries are classified by volume

Lithium-ion batteries can be divided into small batteries and large batteries according to their volume. Lithium-ion batteries can be divided into small batteries and large batteries according to their volume. Battery capacity involves technology and cost. Small batteries are usually used in 3C electronic products. Currently, more than 85% of lithium-ion battery products are small batteries. Large batteries are also commonly referred to as power lithium batteries. There are also low-power batteries and high-power batteries. The former is mainly used for electric bicycles and electric tools, and the latter is used for electric vehicles and energy storage. At present, the three types of electric vehicles (EV), plug-in hybrid electric vehicles (PHEV), and hybrid electric vehicles (HEV) are in a period of rapid development and are attracting attention from the industry. Although the power lithium-ion battery has the disadvantages of high price and poor safety performance, it has important advantages such as large energy and long cycle life, so it has a broader development prospect. As the core of the future automobile industry, the development of the power lithium-ion battery industry has received unprecedented attention and has been elevated to a strategic height by major countries. Small batteries cannot be compared with large batteries in terms of product profit or development scale. Although the power lithium-ion battery industry is still small, the mass production of electric vehicles has brought important development opportunities for the power lithium-ion battery industry. According to industry authority estimates, in recent years, the scale of the power lithium-ion battery market will exceed the global mobile phone lithium-ion battery market. This change will trigger a new round of investment in related manufacturing equipment and plants, and at the same time, it will enter the power lithium-ion battery industry. The important manufacturers will make the competition in related technical fields more intense. At present, the technical method of large-capacity battery using single or small-capacity battery parallel technology solution has always been a debate in the industry. What kind of technical route depends on the result of the battery pack, whether it is size, weight, quality, performance, price competition, installation Convenience, wait. Wang Jinliang, vice president of the my country Battery Industry Association, said that whether the battery pack is connected to a large-capacity single battery or connected in parallel with a small-capacity single battery is not only a technical issue, but also a cost issue. From mathematical probability analysis (quantity), the speed of compound, 10,000 battery product defects and process defects will be greatly increased, and other small batteries use more spare parts, such as housing, accessories, single battery protection (balance) components, such as cost Will be added substantially, even if technically feasible, will eventually be eliminated by the market.
