NO. Item Requirements Test Method
1 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%
