In the 1970s, M. S. Whittingham proposed and began researching lithium-ion batteries. Due to the very active chemical nature of lithium metal, chemical reactions are particularly prone to occur, making lithium metal processing, storage, and use very demanding on the environment. The same lithium battery storage environment largely affects the performance and life of the lithium battery.
Self-discharge of lithium battery
It is well known that lithium battery life is limited, generally 300-500 times. In fact, the life of a lithium battery should be calculated from the moment it leaves the factory, rather than from the first use.
The lithium battery itself is in the self-discharge process before use, and the self-discharge phenomenon of the lithium battery itself is an inevitable phenomenon of all lithium batteries. The self-discharge of lithium batteries 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 ~ 20 °C. So to see the life of a lithium battery depends on the date of production on its packaging.
