2. Conventional Chemical Performance/Electrical Performance Requirements

(1) Appearance structure:

Visual inspection without rupture, scratch, deformation, stain, electrolyte leakage.

(2) Standard Test:

If there is no special requirements of the test should be in 20±5℃ (temperature), 65±20% (humidity) conditions. The ammeter and voltmeter used in the test shall have an accuracy class of 0.5 or less.

(3) Standard charge:

In the environment of 20±5℃, 65±5%RH, the battery was charged with 0.5ItmA current to 4.2V. Then turn to constant voltage 4.2V charging, until the charging current is less than 20mA, stop charging.

(4) Fast Charging:

In the environment of 20±5℃, 65±5%RH, the battery was charged at a constant current of 1500mA to a single battery voltage of 4.2V. Then turn to constant voltage 4.2V charging, until the charging current is less than 20mA, stop charging.

(5) Rated capacity:

In the environment of 20±5℃ and 65±5%H, the battery was charged with a constant discharge current of 0.5mA to a termination voltage of 2.75V. Standard charge after 15 minutes; Discharge capacity at 0.2ITmA to 2.75V. Discharge capacity: ≥100%C5mAh.

(6) Cycle life:

Discharge the battery according to the requirements of the standard discharge and then set aside for 15 minutes. In the environment of 20±5℃ and 65±5%RH, charge the battery for 15 minutes according to the requirements of fast charging, discharge the battery with 1500mA current until the terminal voltage of the battery reaches the termination voltage of 2.75V. Cycle charge and discharge, when the discharge capacity of any cycle is less than 80%CsmAh, the life is terminated. The number of cycles must be greater than or equal to 400.

(7) -20℃ discharge performance:

The battery should be charged according to the standard charging method, and then stored in the ambient temperature of -20 ° C ±2 ° C for 16h~24h.

At -20°C±2°C ambient temperature, the battery is removed with 0.2ima constant current to the termination voltage of 2.75V; Discharge capacity ≥60%C5mAh
