Why does the lithium battery capacity decrease?

Reasons for the decrease in the capacity of the lithium battery 1. Cell aging and degradation 2. Different self-discharge rates, resulting in unbalanced battery cells in series, which ultimately leads to a decrease in the capacity of the lithium battery and not durable 3. It will appear during the use of the battery and the process of charging and discharging. The vulcanization phenomenon affects the capacity of the lithium battery. The vulcanization performance of the battery is: the battery itself is low in voltage, it will be full after charging, and it will be gone after discharging, the battery softening performance is: the liquid inside the battery is turbid and black. The capacity of the battery is reduced, and the lead powder falls off after a long time. 4. Improper charging in summer and winter. The battery charging voltage is inversely proportional to the ambient temperature, so the temperature is high in summer, and the battery is overcharged and the battery loses water, causing the battery to bulge and deform. Driving mileage decreases due to undercharge in winter. Statement: Some pictures and content of articles published on this site are from the Internet.
