Cell Performance | ||||
Item | Test Methods and Condition | Criteria | ||
0.2C Capacity | After standard charging, rest battery for 10min, then discharging at 0.2C to voltage 3.0V, recording the discharging time. | ≥300min | ||
Cycle Life | Constant current 0.5C charge to 4.2V, then constant voltage charge to current declines to 0.01C, rest 10min,constant current 0.5C discharge to 3.0V,rest 10min. Repeat above steps till continuously discharging capacity Higher than 80% of the Initial Capacities of the Cells. | ≥300min | ||
Capability of keeping electricity | 20±5℃, After standard charging, rest the battery 28days, discharging at 0.2C to voltage 3.0V, recording the discharging time. | ≥240min | ||
Discharge at high temperature | After standard charging, rest the cells 4h at 60±2℃, then discharging at 1C to voltage 3.0V, recording the discharging time. | ≥54min | ||
Discharge at low temperature | After standard charging, rest the cells for 16h at -20±2℃, then discharging at 0.2C to voltage 3.0V, recording the discharging time. | ≥210min | ||
Thermal shock | Put the cells in the oven. The temperature of the oven is to be raised at 5±2℃ per minute to a temperature of 130±2℃ and remains 30 minutes. | No fire, no smoke | ||
Over charge testing | At 23±5℃, charging cells with constant current 2C to voltage 5.0V, Stop test till cells temperature 10℃ lower than max temperature. | No smoke or fire | ||
Over discharge testing | At 23±5℃, According to the requirements of standard charge, the cells will be discharge to cut-off voltage, then connect with external load of 30 ohm for 24 hours. | No fire, no smoke, no leakage. | ||
Short-circuit testing | At 23±5℃, After standard charging, connect cells anode and cathode by wire which impedance less than 80±20mΩ, keep 6h. | No smoke or fire | ||
