Introduction of Lithium Battery Discharge

The discharge process of lithium batteries is actually a process of normal use. There are still several aspects that need attention.

1, discharge current can not be too large, too large current causes the battery internal heat, may cause permanent damage;

2, absolutely not over discharge.

(1) Lithium batteries are most afraid of over-discharge. Once the discharge voltage is lower than 2.7 V, it may cause the battery to be scrapped;

(2) The protective circuit has been installed inside the battery, and the voltage is not yet low enough to damage the battery. The protective circuit will function and stop the discharge;

(3) The larger the discharge current of the battery, the smaller the discharge capacity and the faster the voltage drop.

During the process of charging and discharging, lithium ions are embeded/deembedded and inserted/deinserted between positive and negative poles, and are vividly referred to as "rocking chair batteries."
