Tested the initial condition and initial capacity of battery. Store at 25 ± 2 ℃ for 28 days after standard charged, tested the final condition of battery. Then discharge at 0.5C to the discharge cut-off voltage 2.75 V, tested the residual capacity of battery. 0.5C/0.5C tested the recovery capacity of battery. Charge/discharge cycle can be conducted for3 times before meeting the standards

|
Temperature cycle test
|
No leakage,fire,explosion
|
|
Standard charge. Put the battery into20+5℃ chamber: raising the chamber temperature to75+2'℃ for 6h ; reducing the chamber temperature to-40+2℃ for 6h; charge the temperature within 30 minutes; repeating the sequence for 10 cycles;
|

|
Drop
|
No leakage, fire, explosion
|
|
After standard charge ,cells dropped from aheight of 1.5m to the cement floor
|

|
Vibration
|
No leakage, fire, explosion
|
|
After standard charge , cells are fixed on vibration table and subjected to vibration cycling at the rate of 1 Hz per minute between 10 Hz to 55 Hz. The excursion of the vibration is 1.52mm. The test has to be carried out for 90 minutes at x,y,z axes individually

Over discharge
|
No leakage, fire, explosion
|
|
A discharged cells are subjected to a reverse charge at 1C for 90 min.
|
||||
|
2
|
Overcharge
|
No fire, explosion
|
|
After standard charge, after standard charge, continue to charge with a constant current1C/10Vper a cell, holding 1h.
|

|
Short-circuit
|
No fire, explosion
|
|
After standard charge, Cells are stored in temperature of 20±5℃ and 55+5℃, Then short-circuited by connecting the positive and negative terminals with a total external resistance of 80±20mΩ, remain for 24h or the case temperature declines by 20% of the maximum
temperature rise. |

|
Crush
|
No fire, explosion
|
|
After standard charge, Placed the cell in two iron plane moulds , with the most strongly13+1KN pressure for the moment compression. Once the maximum force has been applied, or an abrupt voltage drop of one-third of the original voltage has been obtained, or 10% of deformation has occurred compared to the initial dimension, the force is released
|
||||
|
5
|
Low-pressure
|
No leakage, fire, explosion
|
|
After standard charge, Put cell into the low pressure box, adjust the air pressure in the test chamber is 11.6 KPa, temperature to room temperature, let stand for 6 h.

|
Seawater soak
|
No leakage, fire, explosion
|
|
After standard charge, cells immersed in3.5% NaCl solution (mass fraction, simulation under the normal temperature water composition) simulation under the normal temperature water composition in 2h, The cell completely submerged in water
