What factors will affect the performance and life of lithium batteries?

In the 1970s, M.S. Whittingham proposed and began to study lithium batteries. Because the chemical properties of lithium metal are very active, and chemical reactions are particularly prone to occur, the production, storage and use of lithium metal have very high environmental requirements. Similarly, the storage environment of lithium batteries greatly affects the performance and life of lithium batteries. 1. Self-discharge of lithium battery Lithium battery itself is in the process of self-discharge before use. The self-discharge phenomenon of lithium battery itself is an unavoidable phenomenon for all lithium batteries. The self-discharge of the lithium battery is affected by the ambient temperature and humidity. High temperature and low temperature will accelerate the self-discharge of the battery. It is recommended to store the battery in a dry environment at 0°C to 20°C. Therefore, the life of a lithium battery depends on the processing date on its packaging. 2. The chemical decomposition of lithium storage battery The inside of lithium storage battery is a complex chemical reaction system, which is mainly composed of positive and negative electrode materials, electrolyte, diaphragm and other materials. In addition to the main reaction of lithium ions, there are some other side reactions, such as the decomposition of electrolyte, the dissolution of active materials, and so on. Lithium batteries that have been stored for a long time will be affected if they are in a balanced state. Under normal circumstances, do not mix the battery with metal objects, lest the metal objects touch 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 fire sources, to prevent high temperature and high humidity from affecting the performance and corrosion of lithium batteries.
