4. Test Condition

4.1 Standard Test Conditions

All tests are conducted at temperature 25±2℃, humidity was 15%~90%RH, atmospheric pressure at 86~106kPa.

Unless there are other special instructions, all performance was tested with unused cells within 1 month after production date.

4.2 Standard Charge Method

The "Standard Charge" means in an ambient temperature of 25±2℃,the cell was discharged with 0.5C constant current to cut-off voltage 2.0V,standing 1hour.Then charged it with 0.5C constant current to 3.65V,then change into constant charge mode,until the charging current down to0.05C,then stop charging and standing 1h.

Test method

 

Criteria

5.1

 

High Temperature Discharge Performance

The cell was charged in accordance with 4.2,and stored in an ambient temperature of 55±2℃ for 5h,then

discharged to 2.0V with 1C constant current.After that,then place the cell in the ambient temperature of 25±2℃ for 4h then check its appearance.

1,Retention capacity at 55℃

≥95%

2,No deformation, No crack.

5.2

 

Low Temperature Discharge Performance

The cell was charged in accordance with 4.2,and stored in an ambient temperature of -20±2℃ for 24h,then

discharged to 1.8V with 1C constant current.After that, place it in the ambient temperature of 25±2℃ for 4h, then check its appearance.

1,Retention capacity at -20℃

≥70%

2,No deformation, No crack.

5.3

 

Rate Charge Performance in Normal Temperature

Under the ambient temperature of 25±2℃

  1. ischarged to 2.0V with 1C constant current,stay for 1h.
  2. Charged to 3.65V with 2C constant current,stay for 1h. c.Discharged to 2.0V with 1C constant current.

 

 

 

Capacity retention≥80%

5.4 Rate Discharge Performance in Normal Temperature

 

The cell was charged in accordance with 4.2,then discharge to 2.0V with 3C current in an ambient

temperature of 25±2℃.

 

 

Capacity retention≥95%

5.5

 

 

Charge Retention

 

The cell was charged in accordance with 4.2,and stored in an ambient temperature of 25±2℃ for 28 days,and

then discharged to 2.0V with 1C constant current.

Capacity retention

≥85%

Capacity recovery

≥90%

Cycle Life

(25±2℃)

The cell was charged to 3.65V with 1C CC/CV cut off 0.05C,stayed for 30min;Subsequently,the cell was discharged to 2.0V with constant current 1C,and stayed for 30min;Prior to next charge-discharge cycle.Record

all the cycles until the retention capacity<80%.

 

 

 

≥2000cycles
