Update Characteristics Curves
Note : If the cell is kept as ex-factory status (40±5% SOC, 25℃), the capacity recovery rate is more than 90% of 10A discharge capacity 100% is 2,900mAh at 23℃ with SOC 100% after formation.
Characteristics
Standard charge
This “Standard charge” means charging the cell CCCV with charge current 0.5CmA (1,500mA), constant voltage 4.2V and 150mA cut-off in CV mode at 23℃ for capacity.
Rated charge
Rated charge means charging the cell CCCV with charge current 4A and 100mA cut-off at 23℃
Standard discharge capacity
The standard discharge capacity is the initial discharge capacity of the cell, which is measured with discharge current of 600mA(0.2C) with 2.5V cut-off at 23℃ within 1hour after the standard charge.
Nominal discharge capacity ≥ 2,950mAh Which complying to the minimum capacity of IEC61960 standard.
Rated discharge capacity
The rated discharge is the discharge capacity of the cell, which is measured with discharge current of 10A with 2.5V cut-off at 23℃ within 1hour after the rated charge. Standard rated discharge capacity ≥ 2,900mAh
Initial internal impedance
Initial internal impedance measured at AC 1kHz after standard charge.Initial internal impedance ≤ 26mΩ
Temperature dependence of discharge capacity
Capacity comparison at each temperature, measured with discharge constant current 10A and 2.5V cut-off after the rated charge is as follows.
| Discharge temperature | ||||
|---|---|---|---|---|
| -20℃ | -10℃ | 0℃ | 23℃ | 60℃ |
| 60% | 75% | 80% | 100% | 95% |
Note:
If charge temperature and discharge temperature is not the same, the interval for temperature change is 3 hours. Percentage index of the discharge at 23℃ at 10A (=2,900mAh) is 100%.
Temperature dependence of charge capacity
Capacity comparison at each temperature, measured with discharge constant current 10A and 2.5V cut-off after the rated charge is as follows.
