The operating voltage of the single cell is as high as 3.7V, which is three times that of the nickel-cadmium battery and the nickel-hydrogen battery, and nearly twice that of the lead-acid battery. This is also an important reason for the higher specific energy of the lithium battery. Therefore, when constructing a power battery pack of the same voltage, the number of series connected to the lithium power battery is much smaller than that of the lead acid battery and the nickel hydrogen battery. If the number of single cells in the power battery is higher, the consistency requirement of the single cells in the battery pack is higher, and the life is worse. After the battery pack has problems in actual use, it is generally one or two. The problem with the single cells then caused problems in the entire battery, so it is not difficult to understand why the 48V lead-acid battery has higher feedback than the 36V lead-acid battery. From this point of view, lithium battery is more suitable for the use of the power battery. For example, 36V lithium battery only needs 10 monomers, while 36V lead acid battery requires 18 single cells, that is, 3 12V battery packs, and each 12V lead acid battery has six single cells or six single cells. composition. Lithium-powered batteries usually have two appearances: cylindrical and rectangular. The inside of the battery adopts a spiral wound structure, and is formed by spacing a positive and negative electrode with a very fine and highly permeable polyethylene film insulation material. The positive electrode includes a lithium collector composed of lithium and cobalt dioxide and a current collector composed of an aluminum film. The negative electrode is composed of a lithium collector composed of a sheet-like carbon material and a current collector composed of a copper film. The battery is filled with an organic electrolyte solution. Safety valves and PTC components are also included to protect the battery from damage during abnormal conditions and output short circuits.
