Discharge Characteristics |
Discharge capacity Nominal capacity×100% A)0.2C5A ≥100% B)0.5C5A ≥98% C)1C5A ≥95% |
Standard charge at 0.2C5A under the condition of normal atmospheric pressure and the environmental temperature of 25°C±5°C and 45%~80% RH(unless otherwise specified, storage and charging should be conducted as this regime), then rest for 10min and discharge at 0.2C5A,0.5C5A,1C5A to 30V respectively. Charge/discharge cycle can be conducted for 3 times before meeting the Standards(the same below). |
2 | Normal Storage |
Residual Capacity≥Nominal capacity*85% Recoverable capacity≥Nominal capacity *90% OCV decrease≤3% impendance increase ≤20% |
Measure initial status and initial capacity. Store for 28 days after standard charge, then measure final status and residual capacity at 0.2C5A to 30.0V; After charge/discharge(1C/0.5C) cycle can be conducted for 3 times , measure the recoverable capacity before meeting the Standards(the same below). |
3 | Cycle Life | Discharge Capacity≥Nominal apacity*60% 0.5C discharger |
Measure initial status and initial capacity, then conduct 0.5C discharge cycle for 800 times . Measure last status and last capacity 60% |
