What are the effects of aging of lithium battery packs on battery performance

Under normal temperature or high temperature, leave the lithium battery pack for a period of time for aging. This is beneficial for the electrolyte to fully infiltrate the pole pieces, which is convenient for stabilizing the performance of the lithium battery pack. 2. After the SEI structure restructuring lithium battery undergoes the pre-forming process, a certain amount of SEI film will be formed on the graphite negative electrode inside the battery, but this film has a compact structure and small pores. The battery will be aged at high temperature, which will help the SEI structure reorganization. A loose and porous membrane is formed. 3. Speed u200bu200bup the side reaction to solve the aging, which will help the lithium battery to pass the unstable stage after the formation of the battery as soon as possible. After the active material in the positive and negative electrode materials is aged, it can accelerate the progress of some side reactions, so that the electrochemical performance of the lithium battery pack can be stabilized more quickly. It is normal for lithium battery packs to age, but they are often not used in a limited amount. If they are not used in time, the aging rate will be very fast. You can change the battery electrode or change the charging method to improve the unified charging and discharging process, thereby extending the battery life.
