ItemCriterionTest Method

0.2C dischargring capacity

Discharging capacity is not less than normal capacity

After Standard Charging,rest 5 minutes,then 0.2C discharge to cut-off voltage

1.0C dischargring capacity

Discharging capacity is not less than 90% of normal capacity

After Standard Charging,rest 5 minutes,then 1.0C discharge to cut-off voltage

Cycle life 

The cycle times is not less than 300

Charge:0.5C CC-CV charge to 4.2 V, then current declines to 0.02C
Discharge:0.5C CC discharge to 2.75 V
When the discharge capacity reduced to 80% of rated capacity, stop testing, and record the cycle times.


Discharging capacity is not less than 85% of initial capacity

After Standard Charging,rest the cell for 28 days in the condition of 20±5℃, then 0.2C discharge to cut- off voltage, and record the capacity.
