6.1.3

Cycle Performance

Under the temperature of 23±2

., charge the battery with 0.2C, when

the voltage reaches up to 4.2V charge with constant voltage until the
charge current ≤0.01C, then stop charging, rest for 0.5h, then
discharge with 0.2C to 3.00V. Cycle with the above mode, when the
continuous discharge time

80% stop cycling. The cycle life is

required ≥300times.

6.1.4

Charged Storage

Characteristics

Charge the battery with 0.2C, then shift to charge with constant
voltage until the voltage reaches up to 4.2V, when the charge current

0.01C stop charging; rest under the temperature of 23±2

.for 28d

then discharge with 0.2C to 3.00V. The discharge time is required
≥4.25h.

6.1.5

Storage Characteristics

Charge the battery, which is newly manufactured shorter than 3
months, with 0.2C until the capacity reaches to 40~50%, after resting
for 12 months under the temperature of 23±2

. and the humidity of

45

75%, then charge with 0.2C to 4.2V then shift to charge with

constant voltage, after full-charge rest for 0.5h, then discharge with
0.2C to 3.00V. The discharge time is required ≥4h.

6.2 Safety Test

No

Items

Test method and determinant standard

6.2.1

High Temperature

Characteristics

Under the temperature of 23±2

, after charging the battery with 0.2C

then put the battery into the constant temperature and humidity oven
with 60±2

for 2h, then discharge with 1C to 3.00V. The discharge

time is required ≥51min and the battery should no deformation and
smoking.

6.2.2

Low Temperature

Characteristics

Under the temperature of 23±2

., after charging the battery with

0.2C, then put the battery into the constant temperature and humidity
oven with -10±2

for 16~24h, then discharge with 0.2C to 3.00V.

The discharge time is required ≥3h and the battery should no
deformation and smoking.

6.2.3

Overcharge Protection

Characteristics

After full-charging the battery with 0.2C and set 1.2 times of the
nominal voltage and current as constant current and voltage supply,
then load it to the battery for 8h. It is required the battery should be no
leakage, deformation, smoking and explosion during the test
processes.
