2. Discharge the battery to 2.5V at 1I1(A) and let it stand
1h.
3.Charge the battery with a current of 2I1(A) to 3.65V, the total charging time does not exceed 30min, and let it stand for 1h.
4. Discharge the battery to 2.5V with 1I1(A) current and record
Recording discharge capacity (Ah).
|
Discharge capacity ≥ 85%*initial capacity
|
|
Room temperature rate discharge
|
1. Test temperature: 25±2℃.
2. Fully charge the battery according to 3.15.
3. Discharge the battery to 2.5V at a current of 2I1 (A) and record the discharge capacity (Ah).
|
Discharge capacity≥90%*initial capacity
|
|
High temperature discharge
|
1. Fully charge the battery according to 3.15
2. Leave the battery at 55±2℃ for 5h.
3. Discharge the battery to 2.5V at a current of 1I1(A) at 55±2℃ and record the discharge capacity (Ah).
4. Put the battery at 25±5℃ for 12h and check the battery
Appearance.
|
No deformation, expansion or other abnormal conditions; discharge capacity
≥90%*initial capacity
|
|
Low temperature discharge
|

Cycle life
|
1. Test temperature: 25±2℃.
2. Use constant current and then constant voltage to charge. The constant current is 0.5I1(A) and the constant voltage is 3.65V.
During the constant voltage process, the charging can be terminated until the current drops to 0.05I1(A). Leave it for 30 minutes.
3. Discharge the battery to 2.5V with a current of 0.5I1(A) and let it stand for 30min.
4. Repeat steps 2) and 3) until the battery capacity is less than
70% of the initial capacity, and record the number of cycles.
