What exactly affects the performance and life of lithium batteries

1. The self-discharge of lithium batteries is well known, and the life of lithium batteries is limited, generally 300 times 500 times. In fact, the life of a lithium battery is calculated from the moment it leaves the factory, not from the first time it is used. Lithium batteries are in the process of self-discharge before use, and the self-discharge phenomenon of lithium batteries is an unpredictable phenomenon among all lithium batteries. The self-discharge of lithium batteries is affected by ambient temperature and humidity. High temperature and soft temperature can accelerate the self-discharge of lithium batteries. It is recommended that the battery be stored in a dry environment at 0°C to 20°C. Therefore, the life of lithium batteries depends on the processing date on their packaging. 2. Chemical analysis of lithium battery The inside of a lithium battery is a complex chemical reaction system, which is mainly composed of positive and negative materials, electrolytes and separators. In addition to the critical reaction of lithium ions, there are some other side reactions, such as electrolyte analysis, dissolution of active materials, and so on. Lithium batteries that have been left for a long time will be affected by their internal balance. Under normal circumstances, do not mix the battery with metal objects, so as to prevent the metal objects from contacting the positive and negative electrodes of the battery, causing a short circuit, damaging the battery, or even causing danger. Lithium batteries should be stored in a ventilated and dry environment, away from high temperature and soft fire sources, and be wary of high temperature and soft humidity that affect the performance of the lithium battery and corrode the surface. Knowing the impact of lithium battery storage environment on its performance enables manufacturers and distributors to better control the processing and sales cycle of lithium batteries, and also enables customers to use lithium batteries more reasonably. Manufacturers and distributors must pay special attention to the impact of long-term storage of lithium batteries on their performance!
