Hello, Battery storage performance is an important parameter to measure the stability of overall battery performance. After the battery is stored for a certain period of time, the battery capacity and internal resistance may change to a certain extent. After a period of storage, the electrochemical properties 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.
It is between 20 and 80 mΩ. The chemical composition capacity of ordinary 18650 model cylindrical lithium batteries commonly seen in the market is generally around 150 mAh/g, while the negative pressure value depends on different manufacturers and models and is approximately between 20 and 80 mΩ. The chemical capacity of a lithium battery refers to the amount of charge a battery can store, generalement expressed in mAh/g per unit area.
