4. Electrical Characteristics
| item | Criteria | Test method |
| 3.1 High Temperature Discharge Performance
| Capacity retention at 55℃ :≥95%
| A cell is charged in accordance with 3.2, and stored in high temperature chamber at 55℃for 5 h, then discharged to cut-off voltage at a constant current of 1C. After that, fetch out the cell and place it in the ambient temperature of 25℃±5℃ for 4 h, then check its appearance |
| 3.2 Low Temperature Discharge Performance
| Capacity retention at -20℃ :≥70%
| A cell is charged in accordance with 3.2, and stored in certain ambient temperature for 24hours,then discharged to cut-off voltage(1.8V) at a constant current of 1C. After that , fetch out the cell and place it in the ambient temperature of 25℃±5℃for 4hours. |
| 3.3 Rate Charge Performance in Normal Temperature
| 2C charge capacity≥80%
| Under the ambient temperature of 25℃±5℃, a, 1C constant discharge till the cut-off voltage, standby for 1h; b, charge at 2C current till 3.65V, standby for 1h; c, constant discharge with 1C current till 2.0V.
|
| 3.4 Rate Discharge Performance in Normal Temperature
| 3C discharge capacity≥95%
| A cell is charged in accordance with 3.2, then discharged to cut-off voltage at certain current in an ambient temperature of 25℃±5℃.
