Self Discharge Of The Lithium Battery Pack

The lithium battery will cause its power loss for various reasons regardless of whether it is used or not. After the battery is fully charged, it is placed for one month. Then it is discharged to 3.0V with 1C, and its capacity is recorded as C2. Recorded as C0, 1-C2/C0 is the monthly self-discharge rate of the battery. The industry standard lithium-ion battery monthly self-discharge rate is less than 12%. The battery self-discharge is related to the battery placement performance, its size is related to the internal resistance structure material properties of the battery.
