Introduction to car ternary lithium battery maintenance

Ternary polymer lithium battery refers to a lithium battery that uses lithium nickel cobalt manganese ternary cathode material as the cathode material. There are many kinds of cathode materials for lithium batteries, including lithium cobalt oxide, lithium manganate, lithium nickelate, ternary materials, and lithium iron phosphate. At present, ternary material batteries have replaced the previously widely used lithium cobalt oxide batteries and are widely used in the field of notebook batteries. In recent years, ternary lithium batteries have also begun to be used in the neighborhood of electric vehicles. If the battery is not used for a long time, it is best to charge about 40% of the power and store it at a temperature of 10~30℃, and recharge it every six months or so; protect the chip lithium battery from the current when charging and discharging The voltage has very strict requirements. In order to protect the battery from damage due to abnormal external electrical environment, a chip that manages the battery status is installed inside the battery body. This chip also has the function of recording battery capacity and correcting battery capacity. At present, even counterfeit mobile phone batteries will not save this key protection chip, otherwise the counterfeit mobile phone battery will not be used for a long time; a common phenomenon on Ni-MH rechargeable batteries with memory effect. The detailed performance is: If you start using the battery without overflowing for a long time, the battery's power will drop significantly, even if you want to overflow in the future, you will be dissatisfied. Therefore, the most important way to maintain the Ni-MH battery is: the battery must be used up before charging can be started, and the battery can be used only when the battery is overflowing. The memory effect of lithium batteries commonly used today is negligible. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
