What are the basic reasons for the shorter life of lithium-ion batteries

1. The choice of materials for lithium-ion batteries is the most important reason. Choose poor quality materials, no matter how good the process technology is, it cannot be guaranteed. 2. The electrolyte volume of lithium-ion batteries. The electrolyte is important to transmit lithium ions between the positive and negative poles. The lack of electrolyte volume is generally due to the lack of injection volume during production and the two reasons why the battery is consumed for a long time. . Insufficient amount of electrolyte will slow down the transmission speed of lithium ions, thereby consuming power and reducing voltage. 3. Moisture. Excessive moisture will affect the positive and negative electrodes in the lithium-ion battery, as well as side-reactions with the active materials of the positive and negative electrodes, destroying the internal structure and affecting the cycle life of the lithium-ion battery. 4. Charging and discharging will eventually reduce the active material of the battery and cause changes in other chemical materials, which will lead to an increase in internal resistance and permanent capacity loss. However, permanent capacity loss occurs even when the battery is not in use. 5. Loss of negative electrode active material, such as negative electrode active material shedding, binder decomposition and other factors, will cause part of the negative electrode active material particles to lose their conductive connection with the conductive network, making it impossible to insert lithium and causing loss of lithium-ion battery capacity. 6. The improper working environment of the lithium ion battery directly affects the length of life: the charging temperature of the lithium ion battery is 0℃～45℃, and the discharge temperature of the lithium ion battery is -20℃～60℃. 7. Charge the battery in a high temperature environment. The performance of the battery is unstable under high temperature conditions. For example, if the battery is charged immediately after exposure to the sun or placed in a high temperature environment, the heat dissipation is not good, and the battery life will be shortened. 8. Insufficient charging frequently. Frequent under-charging can easily lead to insufficient battery capacity. If the battery is under-charged for a long time, it can easily lead to failure to fully charge in the future, affecting travel and service life.
