Mechanical Performance
Item Measuring procedure Requirements
Cycle Life Carry out 500cycle.
Charge/discharge follow the below condition
Charge: 1.0C charge to 4.2V, cut off at 10mA
Discharge: 1200mA discharge for 5s, then rest 10s
Cycle above discharge steps to 3.3V
Rest time between charge/discharge: 30 minimum
Temperature: 25 ±2°C
Higher than 80% of the initial capacity
Impact Test Cell is to be placed on the impact flat
56mm diameter bar is inlayed into the bottom, 10kg weight is to be dropped from a height of 1m onto the cell, the distortion is allowed
no explosion, no fire
Forced discharge discharge at a current of 1C for 2.5H no explosion, no fire
Nail pricking prick through the sample battery with a nail having a diameter of 3mm and remain 2h no explosion, no fire
Vibration test after standard charge, the battery is to be tested as following conditions:
Amplitude: 0.19mm
Frequency: 10~55Hz (sweep: 1Hz/minimum)
Direction: X/Y/Z axis for 30 minimum
battery is to be tested in three mutually perpendicular to each axis
no fire, no explosion, no smoking
Drop test drop the battery in the shipment condition (full- charge) from 1m height onto 18~20 mm or thicker concrete with p-tile on it 1 times each of obverse and inverse directions at 25 ±2°C no fire, no explosion, no smoking
Constant humidity and temperature characteristics Under the temperature of 20 ±5°C, after charging the battery with 0.2C, then put the battery into the constant temperature and humidity oven with 55 ±2°C and 90-95% for 48h, the battery should be no obvious deformation, leakage, rust, smoking and explosion
After testing take out the battery then rest for 2H under the temperature of 20 ±5°C, discharge with 1C to 3.0V
discharge capacity ≥60% C5
Short-circuit test After standard charge, the battery is to be short-circuited by connecting the positive and negative terminals of the battery with copper wire having a maximum resistance load of 0.1Ω no explosion, no fire temperature of the exterior cell casing shall not exceed 160°C
Heating test battery is to be heated in a gravity convection or circulating air oven
temperature of the oven is to be raised at a rate of 5 ±2°C/minimum to a temperature of 130 ±2°C at which temperature the oven is to remain for 30 minutes before the test is discontinued
no explosion, no fire
Abnormal charging test after standard charge, the battery is subjected to a charging current by connecting it to a dc-power supply
beginning current is 3.0C, which is to be obtained by connecting a resistor of specified size and rating in series with the battery
voltage of the DC-power supply is 4.6V
test time is 2.5 hours
no explosion, no fire
Over-discharge test fully discharged cell is continually discharged for 24H with the (30x n) Ω load at 23± 2°C no explosion, no fire
High temperature characteristics
within 2H leave the battery in constant temperature and constant humidity box which temperature is 55 ±2°C after fully charge, discharge at 1C to 3.0V
discharge time is required ≥51 minimum
no deformation and smoking
Low temperature characteristics
after fully charge, leave the battery in constant temperature and constant humidity box which temperature is -10±2°C for 16-24H, discharge at 0.2C to 3.0V
discharge time is required ≥3H
no deformation and smoking
