18650 2500mAh 3.7V high rate lithium battery Cell:
18650 lithium battery cell Safety Testing :
Over charge, over discharge, hot oven test, High Teerature Test ,
low teerature test, humidity test,
vibration test, drop test, collisions, crush, short circuit, iact,
thermal shock, constant da performance
| Test Methods and Condition | |
| After standard charging, rest battery for 10min, then discharging
at 0.2C to voltage 3.0V, recording the discharging time. | |
| Constant current 0.5C charge to 4.2V, then constant voltage charge
to current declines to 0.01C, rest 10min, constant current 0.5C
discharge to 3.0V, rest 10min. Repeat above steps till continuously
discharging capacity higher than 80% of the initial capacities of
the cells. | |
Capability of keeping electricity | 20±5℃, after standard charging, rest the battery 28days,
discharging at 0.2C to voltage 3.0V, recording the discharging
time. | |
Discharge at high teerature | After standard charging, rest the cells for 4h at 60±2℃, then
discharging at 1C to voltage 3.0V, recording the discharging time. | |
Discharge at low teerature | After standard charging, rest the cells for 16h at -20±2℃, then
discharging at 0.2C to voltage 3.0V, recording the discharging
time. | |
| Put the cells in the oven. The teerature of the oven is to be
raised at 5±2℃ per minute to a teerature of 130±2℃ and remains 30
minutes. | |
| At 23±5℃, charging cells with constant current 3C to voltage 5.0V,
then with constant voltage 5.0V till current decline to 0. Stop
test till cells teerature 10℃ is lower than max teerature. | |
| At 23±5℃, according to the requirements of standard charge, the
cells will be discharge to cut-off voltage, then connect with
external load of 30 ohm for 24 hours. | No fire, no smoke, no leakage. |
| At 23±5℃, after standard charging, connect cells anode and cathode
by wire which iedance less than 50mΩ, keep 6h. | |
