stays for 1 hour. At 25 ±5°C, discharge the battery
at constant current 0.5 C until 2.75 V cut-of voltage.
Then the battery stays for 1 hour. A cycle defned as
one charge and discharge. This charge and discharge
circle shall be repeated 500 times|The capacity at 500th cycle
≥ 80% of the nominal
capacity| |Electricity
Preservation|After the charge according to 2.2.1, the battery stays
at 20 ±5°C for 28 days and then discharge at 0.2 C to
2.75 V cut-of|The discharge capacity
80% of the nominal capacity| |High Temperature
Performance|After the charge according to 2.2.1, store the testing
cells at 60 ±2°C for 4 hours. Then discharge at 1 C
until 2.75 V cut-of voltage|The discharge capacity
90% of the nominal capacity| |Low Temperature
Performance|After the charge according to 2.2.1, store the testing
cells at -20 ±2°C for 16 to 24 hours. Then discharge at
0.2 C until 2.75 V cut-of voltage|The discharge capacity
60% of the nominal capacity| |Short-circuit|After the charge at 2.2.1, short circuit the cathode and
anode. Stop testing when battery temperature decays
to about 10°C from the maximum temperature|No fre, no explosion| |Overcharge|Put the testing batteries connecting with thermocouple
in ventilated cabinet, connect the cathode and anode
to a power supply with CC / CV (constant current /
constant voltage) function. Adjust the current to 3 C
and voltage to 4.6 V. Then charge the battery at 3
C until the limit voltage reaches 4.6 V. The charging
continued for 8 hrs|No fre, no explosion| |Hot Box Test|Put the testing batteries connecting with thermocouple
in constant temperature box. Heat the batteries and
box (speed of ascending temperature is 5 ±2°C
at room temperature simultaneously). Monitor the
temperature change of the box. Keep for 10 minutes
after the box temperature reaches 150 ±2°C, then stop
the test|No fre, no explosion| |Vibration Test|After the charge at 2.2.2, put the testing battery on
the vibration testing equipment. Vibrate it from X,Y
two diferent directions for 30 minutes (Frequency
of vibration: 10 Hz - 30 Hz, displacement of single
swing: 0.38 mm; Frequency of vibration: 30 Hz- 55 Hz,
displace of single swing: 0.19 mm) in swept vibration
from 10 Hz to 50 Hz. The swept rate is 1 oct / min.|No fre, no explosion ≥ 90%
of the nominal capacity| |Drop Test|After the charge at 2.2.2, free drop the testing battery
from the height of 1 meter (the lowest point height)
once from the each six positive and negative X, Y, Z
directions to the hardwood board (the thickness of the
board is about 50 mm)|No fre, no explosion ≥ 90%
