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℃. |
3.5 Cycle Life (25℃±5℃) | ≥2000cycles | A cell is 1C CC/CV 3.65V fully charged, after that stored for 30min;Subsequently, the cell is discharged to cut-off voltage at a constant current of 1C, and stored 30min prior to next charge-discharge cycle, until the capacity retention＜80%, and record all the cycles |
4. Safety Performance
| Item | Test name | Result |
| 1 | Over charge | No fire,no explosion |
| 2 | Over discharge | No fire,no explosion |
| 3 | Short Circuit | No fire,no explosion |
| 4 | Drop | No fire,no explosion,no leakage |
| 5 | Hot oven | No fire,no explosion |
| 6 | Crush | No fire,no explosion |
| 7 | Needle puncture | No fire,no explosion |
