Why do the batteries have to be stored for a while before they can be packaged

The storage performance of the battery is an important parameter to measure the overall stability of the battery. After the battery has been stored for a certain period of time, the capacity and internal resistance of the battery are allowed to change to some extent. After a period of storage, the electrochemical performance of the internal components can be stabilized, and the self-discharge performance of the battery can be understood to ensure the quality of the battery.
