Electrical Characteristic for High temperature resistance lithium ion battery
NO. | Item | Standard | Test Method |
1 | Discharge rate capabilities | A)1 C ≥97% B)5 C ≥95% B)10 C ≥95% | Standard charged under the condition of normal atmospheric pressure and the environmental temperature of 23℃±3℃ and45%~85%RH, then rest for 30mins and discharge at1C、5 C 、10C to the discharge cut-off voltage respectively. Charge/discharge cycle can be conducted for 3 times beforemeeting the Standards(the same below) |
| capacity retention and recovery | Residual capacity≥94%Recoverable capacity≥*98% | Standard charged under the condition of normal atmospheric pressure and the environmental temperature of 23℃±3℃,Stored for 28 days, then discharge at 0.2 C to 2.75V measuring residual capacity; Then standard charge/discharge measure recoverable capacity. |
3 | Low TemperaturePerformance | discharge capacity≥85% rated capacityno distortion and no rupture | The cell shall be charged in accordance with the standard charge. Then stored in the temperature of -10℃±1℃ for4h, Discharge at the constant current of 0.2C down to the end-of-discharge voltage 2.50V. |
4 | Cycle Life | 2A charge/ 10Adischarge≥500cycles4A charge/ 20Adischarge≥200cycles | Charge: The cell shall be charged in accordance with2A(4A)Charge condition and the end-of-charge voltage is4.15V. rest for 30mins.Discharge:10A discharge to 2.75V, one cycle is finished, rest for 60mins. Then repeat above steps, when capacity is lessthan 70% of initial capacity, the battery life is over. Discharge:20A discharge to 2.75V, one cycle is finished, rest for 60mins. Then repeat above steps, when capacity is lessthan 70% of initial capacity, the battery life is over. |
Safety Characteristic for 2000mAh Li-ion battery supplier
NO. | Item | Standard | Test Method |
1 | Overcharge | No fire、No explosion | After standard charge, rest for 10mins; then charge at constant current of 3C5A to 10V.(or charge at 3C5A for 90mins). |
2 | Forced discharge | No fire、No explosion | The battery to be discharged with standard discharging condition, Inverse charge current =1C5A;time: ≥ 90mins |
