The specific energy is large. The actual specific energy that can be achieved at present is 100-115Wh/kg and 240-253Wh/L
The cycle life is long, generally up to 500 times.
Good safety performance, no pollution, no memory effect. As the predecessor of Li-ion, the lithium battery is prone to short circuit of dendrites due to metal lithium, which reduces its application fields: Li-ion does not contain cadmium, lead, mercury, and other elements that pollute the environment.
The self-discharge is small, and the self-discharge rate of Li-ion fully charged at room temperature for one year is about 10%
Unless otherwise specified, this specification item test should be performed in the test under the condition of normal atmospheric pressure.
Measuring instrument and equipment requirements
Standard charging mode
Standard temperature 25±3℃ Charging battery consists of charging at a constant current rate of 0.2 C5A until the battery voltage reaches 4.2V .then battery be charged at a constant voltage of 4.2V while tapering the charge current. Terminal charge until the charging current drops to 0.02C. Anyway, the total charge time for one cycle is not more than 8 hours.
Standard Discharge mode
Standard temperature 25±3℃ discharge to the cut-off voltage with 0.2 C5A current.
The standard charge mode for charging, then the standard discharge mode to discharge, measured for the first time the battery capacity is the initial capacity.
