Quality Testing
| Items | Test Conditions | Specification |
Standard Charge | The "Standard Charge" means charging with constant current 0.2C5 to3.65V, then charging with constant voltage 3.65V to 0.01C 5
under 20±5 , ℃ charging time will not more than 8h.) (Use
Lithium-ion battery charger, which with an accuracy ±0.05V. | |
Nominal Capacity |
The capacity means the discharge capacity of the cell, which is
measured with discharge current 0.2C5A to cut-off voltage at 2.0V at 20±5℃ rest for 30 minutes after the
Standard Charge. |
Nominal Capacity ≥6000mAh |
Cycle Life | After 2000 cycles of charge and discharge, the discharge capacity
is measured with 0.2 C5A discharge current and 2.0V cut-off voltage. |
≥80%Nominal Capacity |
(Storage Characteristic) |
Test the cell initial capacity using 0.2C 5 current at 23±2℃ and
record,then charge the cells with 45% capacity, then storage for 3,
6, 12 months respectively at 20±5℃and relative humidity of 45%~75%,
then the cell is cycled for 5 times with charge with 0.2C5A and discharge with 0.2C5A at 23±2℃, The maximum discharge capacity (longest discharge time) is recorded. | 0.2C5Adischarge time: After 3 months storage ≥4.5hrs; After 6 months storage ≥4.25hrs;
