Characteristic of High security rechargeable lithium battery

Without special instructions, the following tests should be done under the condition of : temperature(23℃±3℃), atmospheric pressure (86KPa～106KPa), relative humidity (45%～85%), and the tests should be done within two weeks after receiving the products.

the definitions of some nomenclatures of this specification

standard Charge: Charge with current 0.2C5A to limit charge voltage under the condition of23℃±3℃

surrounding temperature,then change to charge with constant voltage till the current less than or equal to0.02C5A.

Electrical Characteristic for Long life lithium ion battery

NO.	Item	Standard	Test Method
1	Discharge rate capabilities	A)1 C5A ≥100% B)10 C5A ≥95% C)15 C5A ≥90%	Standard charged under the condition of normal atmospheric pressure and the environmental temperature of 23℃±3℃ and45%～85%RH, then rest for 30mins and discharge at1C5A,5 C5A,10 C5A to the discharge cut-off voltage respectively. Charge/discharge cycle can be conducted for 3times before meeting the Standards(the same below)
2	capacity retention and recovery	Residualcapacity≥94％ Recoverablecapacity≥*98％	Standard charged under the condition of normal atmospheric pressure and the environmental temperature of 23℃±3℃, Stored for 28 days, then discharge at 0.2 C5A to 2.75Vmeasuring residual capacity; Then standard charge/discharge measure recoverable capacity.
3	Low Temperature Performance	discharge capacity≥85% rated capacityno distortion and no rupture	The cell shall be charged in accordance with the standard charge. Then stored in the temperature of -10℃±1℃ for4h, Discharge at the constant current of 0.2C5A down to the end-of-discharge voltage 2.75V.
4	Cycle Life	≥300cycles	Charge: The cell shall be charged in accordance with RapidCharge condition. rest for 10mins.Discharge: 10C5A discharge to 2.75V, one cycle is finished, then rest for 30mins. Then repeat above steps, when capacity is less than 80% of initial capacity, the battery life is over.

Ship

The cells might be damaged during shipping by shock. If any abnormal features of the cells are found such as deformation of the cell package, smelling of an electrolyte, an electrolyte leakage and others, the cells shall never be used any more. The Cells with a smell of the electrolyte or a leakage shall be placed away from fire to avoid firing.

Storage

The cell shall be stored at the environmental condition of -20℃ - 45℃ and 65%±20% RH. The voltage for long time storage shall be 3.6V-3.9V range. If the cell has to be storied for a long time (Over 3 months), the environmental condition should be: Temperature: 23℃±3℃ Humidity: 65%±20％RH; please activate the battery once every 3 months according to the following method: Charge with current 0.2C5A until the voltage achieve to 4.0V.
