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

Item	Test Methods and Condition	Criteria
0.2C Capacity	After standard charging, rest battery for 10min, then discharging at 0.2C to voltage 3.0V, recording the discharging time.	≥500min
Cycle Life	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.	≥500 times
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.	≥240min
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.	≥54min
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.	≥210min
Thermal shock	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.	No fire, no smoke
Over charge testing	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.	No smoke or fire
Over discharge testing	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.
Short-circuit testing	At 23±5℃, after standard charging, connect cells anode and cathode by wire which iedance less than 50mΩ, keep 6h.	No smoke or fire
