Item

Testing method

Requirement

1. Capacity

 

Discharge the battery at a constant current of 1Cto 3.0V after Standard Charge and rest 30min

 

Discharge Capacity≥

100%(Nominal Capacity)

2. C-rate Discharge Characteristics

 

Discharge the battery at a constant current of 10C to 3.0V after Standard Charge

 

Discharge Capacity≥98%(10 C)

3. Cycle Life characteristics

 

Measure capacity under the cycle conditions described below, until the discharge capacity ≤80%(10C) for three times. Cycle conditions: Standard Charge(CC-CV,10C,4.2V),Rest for 30min; Discharge at 0.5C to 3.0V cut-off. Testing temperature is 23±2℃

 

 Life≥300 cycles

 

 

Discharge Capacity≥80%(10C)

4. High and low temperature performance

 

After full charge under the condition of 23 ℃, measure the capacity ( compared with initial capacity ) of the cell core at different temperature and discharge with 0.2 c current to 3.0V.
