Safety Lithium Ion Battery Module With Prismatic ABS / Metal Case

1. Lithium battery module advantage

Green product: LiFePO4 material is no harm to enviroment and human being .
Cycle life: More than 2000 cycle times
Very safe: It have the best safety and steady performance,no fire ,no exploding under the condition of over-charge.
Light weight and smaller dimension: The dimension compares with other battery.about 1/2-2/3 weight of lead acid
Great capacity and more powerful,rechargeable battery: We can install many single cells in series and in parallet and it can fully discharge
No memory effect: It can be recharged anytime,no reduction of the capacity

2. Battery cells Environmental Characteristics

No.	Item	Test Method	Criteria
5.1	Temperature shock test	A cell is charged in accordance with 3.2, and then repeat the following procedures for 5 cycles, then check the cell's appearance.	No leakage, no fire, no explosion, no vent
5.2	Low-pressure Test	A cell is charged in accordance with 3.2, then stored for 6h at a vacuum of -90KPa, after that put the cell in room temperature for 6h, then check the cell's appearance.	No leakage, no fire, no explosion, no vent
5.3	Vibration Test	A cell is charged in accordance with 3.2, and then installed onto the vibration machine. Equipment parameters of frequency and amplitude are set as bellow (the frequency is to be varied at the rate of 1oct/min between 10 and 55 Hz, and repeat vibration for 30 min. The cell is tested in three mutually perpendicular directions, i.e. X,Y,Z): (a) frequency:10Hz~30Hz, amplitude: 0.38mm; (b) frequency:30Hz~55Hz amplitude: 0.19mm	1.No scratch, no fire, no explosion, no vent; 2.The voltage is not less than 3.2V.
5.4	Shock Test	A cell is tested in accordance with 3.2, and then secured to the testing machine by means of rigid mount which supports all mounting surfaces of the cell. Each cell shall be subjected to a total of three shocks of equal magnitude. The shocks are to be applied in each of three mutually perpendicular directions. The acceleration and impulse time are as follows: acceleration of impulse peak value: 100m/s², shock frequency:40~80 times/min, impulse lasting time:16 min,shock times:1000±10	1.No scratch, no leakage, no fire, no explosion, no vent; 2.the voltage is not less than 3.2V.

3. Electrical Characteristics

item	Criteria	Test method
3.1 High Temperature Discharge Performance	Capacity retention at 55℃ :≥95%	A cell is charged in accordance with 3.2, and stored in high temperature chamber at 55℃for 5 h, then discharged to cut-off voltage at a constant current of 1C. After that, fetch out the cell and place it in the ambient temperature of 25℃±5℃ for 4 h, then check its appearance
3.2 Low Temperature Discharge Performance	Capacity retention at -20℃ :≥70%	A cell is charged in accordance with 3.2, and stored in certain ambient temperature for 24hours,then discharged to cut-off voltage(1.8V) at a constant current of 1C. After that , fetch out the cell and place it in the ambient temperature of 25℃±5℃for 4hours.
3.3 Rate Charge Performance in Normal Temperature	2C charge capacity≥80%	Under the ambient temperature of 25℃±5℃, a, 1C constant discharge till the cut-off voltage, standby for 1h; b, charge at 2C current till 3.65V, standby for 1h; c, constant discharge with 1C current till 2.0V.
3.4 Rate Discharge Performance in Normal Temperature	3C discharge capacity≥95%	A cell is charged in accordance with 3.2, then discharged to cut-off voltage at certain current in an ambient temperature of 25℃±5℃.
3.5 Cycle Life (25℃±5℃)	≥2000cycles	A cell is 1C CC/CV 3.65V fully charged, after that stored for 30min;Subsequently, the cell is discharged to cut-off voltage at a constant current of 1C, and stored 30min prior to next charge-discharge cycle, until the capacity retention＜80%, and record all the cycles

4. Safety Test

No.	Item	Test Method	Criteria
4.1	Short- circuit Test	A cell is tested in accordance with 3.2, after that the cell is short-circuited by connecting the positive and negative terminals with a wire for 10min, the wire has a maximum resistance load of 5mΩ., then observe for 1h.	No fire, no explosion
4.2	Overcharge Test	A cell is tested in accordance with 3.2, then 1C constant current charged till the voltage reaches 1.5 times of the specified end-off charge voltage, or the charge time reaches 1h, then stop charge, and observe for 1h.	No fire, no explosion
4.3	Over discharge test	A cell is tested in accordance with 3.2, then 1C discharge for 90min, then observe for 1h.	No fire, no explosion, no leakage
4.4	Crush Test	A cell is tested in accordance with 3.2, and then is placed on the crush machine, the axis is parallel to the crush equiment, and it is crushed between two flat surfaces till the crushing force is gradually approaching 200 kN, or voltage reaches 0V,or reaches 30% distortion, then observe for 1h.	No fire, no explosion
4.5	Impact Test	A cell is tested in accordance with 3.2, and then placed on the impact flat. A Φ15.8mm bar is to be placed on the center of the cell. A 9.1kg weight is dropped from a height of 610mm onto the cell, the distortion is allowed.	No fire, no explosion
4.6	Stick Test	a) A cell is tested in accordance with 3.2 b) use φ5mm～φ8mm high temperature resistance steel needle, with speed of 25±5mm/s, to go through the cell from vertical direction of pole plate, the penetrate position should be close to the geometric center of plate surface, the steel needle remains in the cell;	No fire, no explosion
4.7	Heating Test(130℃)	A cell is tested in accordance with 3.2, and then heated in a circulating air oven. The temperature of the oven is raised at a rate of 5℃ per minute to 130℃±3℃ and remain for 30 min.	No fire, no explosion
