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. |
