What is the reason for the shorter life of lithium-ion batteries?solar energy storage lithium ion battery 10kwh 48v 100ah

　　1. The choice of lithium ion battery materials is the most important reason. The selection of materials with poor quality can not be guaranteed no matter how good the technology is.

　　2. The electrolyte volume of lithium ion battery. The main function of electrolyte is to transmit lithium ions between the positive and negative poles. The shortage of electrolyte volume is generally due to the insufficient liquid injection during production and the consumption of the battery for a long time. Insufficient electrolyte will slow down the transmission speed of lithium ion, thus consuming power and reducing voltage.

　　3. Water, too much water will affect the positive and negative poles in the lithium-ion battery, and will also have side reactions with the active substances of the positive and negative poles, which will damage the internal structure and affect 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, thus causing internal resistance increase and permanent capacity loss. However, even when the battery is not in use, permanent capacity loss will occur.

　　5. The loss of the negative active material, such as the loss of the negative active material, the decomposition of the adhesive and other factors, will cause some negative active material particles to lose the conductive connection with the conductive network, thus making it unable to embed lithium, resulting in the loss of lithium ion battery capacity.

　　6. Improper working environment of lithium-ion batteries will directly affect the length of service life: the charging temperature of lithium-ion batteries is 0 ℃~45 ℃, and the discharge temperature of lithium-ion batteries is - 20 ℃~60 ℃.

　　7. Charge the battery under high temperature. The performance of the battery is unstable under high temperature conditions. For example, charging the battery immediately after exposure to the sun or charging it under high temperature environment will lead to poor heat dissipation and shortened battery life.
