Characteristics testing:

item	test method	Requirements
Charging/Cut-off Voltage	4.20±0.01V
Discharge/Cut-off Voltage	3.00±0.01V
Standard Charge	Charge the battery at constant current of 0.2C to reach 4.2V. Then charge the battery at constant 4.2V voltage until , the charging current decreasing to 0.01C.	Charging time≤8h
Standard Discharge	After the standard charging,rest for 1 hour then discharge, to 3.0V 0.2c
Rate Discharge	After the standard charging,rest for 1 hour then discharge, to 3.0V 0.5C	Discharging time≥102Min
High Temperature Characteristics	Fully charging, store them at (55±2)℃ for 2 hours, then discharge to 3.0V @0.5C	Discharging time ≥102 Min , No transform, no explosion,no fire,no leakage
Low Temperature Characteristics	Full charging, store them at (-10±2)℃ for 16-24 hours, then discharge to 3.0V @0.2C	Discharging time ≥255 Min, No transform, no explosion,no fire,no leakage
Capacity retention	Fully charging, store them at (20±2)℃ for 28 days, then discharge to 3.0V 0.2C	Discharging time ≥255 Min, No transform, no explosion,no fire,no leakage
Cycle Life 25℃	Charge the battery @0.5C to reach 4.2V. Then charge the, battery at constant 4.2V voltage until the charging current, decreasing to 0.01C. Rest for 10 min. discharge to 3.0V 0.5C and rest for 10 min. Continue the charge/discharge cycles until discharge capacity lower than 80% of rated capacity	Cycle life ≥500
Storage	Charge the battery to 40%~65% of its rated capacity using, standard charging mode, then keep it in an 20℃±5℃, humidity 45%~85% room for 12 months. Discharge it 0.2C until voltage down to 3.0V	Discharge time ≥240Min

Environment Characteristics:

Item	Testing Method	Requirements
Hot & humidity testing	Full charging, store it at 40±2℃ with 90%~95RH% for 48 hours. Then put the battery at room temperature 20±2℃ for 2 hours. Then discharge to 3.0V 0.5C	Discharging time ≥72 Min no transform, No erosion, no explosion,no fire,no leakage
Vibration	After Standard Charging,fixed the battery to vibration table,then subjected to vibration test for 30 minutes per axis of XYZ axes	No explosion,no fire, no leakage. Voltage≥3.7V.
Shock test	After Standard Charging,test condition Acceleration :100m/s2 Crash time per min: 40-80 times, Pulse lasting time : 16ms , Shock times : 1000±10times	No explosion, no fire, no leakage. Voltage≥3.7V.
Drop Test	After standard charging , drop the battery from 100cm, height onto a 18mm~20mm thick hardwood. Two sides of X,Y,Z directions each (total 6 times) After the drop test, discharge the battery 0.5C to 3.0V Then charge it 0.5C to full capacity.

Safety Performance

Overcharge protection test	After standard charging. Apply a 7.4V stable Voltage and 1C stable current to the battery for 8 hours	No fire, no explosion
Over discharge protection test	After discharged to the cut-off voltage,the battery shall be subjected to a short-circuit condition with a load of resistance less than 30Ω for 24 hours	No fire, no explosion
Short circuiting protection test	After standard charging,the battery shall be subjected to a short-circuit condition with a wire of resistance less than 100mΩ for 1 hour. Cut off the circuit, Charge the battery with constant current at 1.0C for 5s	No fire, no explosion, Voltage≥3.7V
Impact Test	After standard charge,Place the battery on a flat surface. A 9.1 kg article is to be dropped from a height of 100cm onto the sample. The battery is allowed to transform	No fire, no explosion
Heating Test	After standard charging,a battery is to be heated in an oven convection or circulating air oven. The temperature of the oven is to be raised at a rate of 5±2℃/min to a temperature of 130±2℃ and last for 30 minutes.	No fire, no explosion
Over charge	After standard charging, put the battery in fume hood. Add constant voltage & current 4.8V 3C to the battery. Charging it until the battery reaches 4.8V, charging current decreases to almost 0A. Record the temperature curve of the battery. When the battery temperature decreases to about 10℃ lower after reaching the peak temperature. End the test. This test is performed without PCM	No fire, no explosion
Short circuiting test	After standard charging, put the battery in fume hood. Connect the Negative Pole and Positive pole directly. (the wire’s resistance should below 50mΩ. Record the battery’s temperature curve during the test. When the battery temperature decreases to about 10℃ lower after reaching the peak temperature. End the test. This test is performed without PCM	No fire, no explosion
