2.Electrical performance for EVE 304Ah cell

No.	Item	Requipments	Measuring Procedure
1	C-Rate DisCharge Performance at 25℃	Discharge Capacity/ Typical Capacity×100% A） 0.5C(A)≥100% B）1.0C(A)≥100%	After standard charge and 1h  rest, discharge to 2.5V cutoff with the current of 0.33C(A), 0.5C(A), 1C(A) respectively. Repeating 3 times, if the capacity is not qualified.
2	Discharge performance at different temperatures	Discharge Capacity/ Typical Capacity×100%A) 55℃时≥95%B) -20℃时≥70%	After standard charge and 5h rest at 55±2℃, discharge to 2.5V cutoff with the current of 1.0C(A)；After standard charge and 24h rest at-20±2℃, discharge to 2.0V cutoff with the current of 1.0C(A)；
3	Charge Retention and Recovery at 25℃	Remaining Capacity ≥ Typical Capacity ×95% Recovery Capacity≥Typical Capacity ×97%	After standard charge and open the circuit for 28 days at 25 ℃ , discharge to 2.5V cutoff with the current of 1.0C(A),  recorded as remaining capacity ； After standard charged and 30mins rest, discharge current 1.0CA with 2.5V cut-off at (25 ± 2) ℃ ， recorded as RecoveryCapacity.
			At 25 ± 2 ℃ ， the battery under 300kgf
			fixture ： charging the cell with charge
4	Cycle Life at 25℃	≥3500 cycles @1C/1C	current 1.0C(A) and constant voltage 3.65V,0.05C cut off,rest for 30min,discharge to 2.5V cut off with the current of 1.0C(A),rest for 30min,and then start the next cycle,end with the capacity decrease to 80% of the initial capacity.The number of cycles is defined as the cycle lifeof the battery
			At 45 ± 2 ℃ ， the battery under 300kgf
			fixture ： charging the cell with charge
5	Cycle Life at 45℃	≥1800 cycles @1C/1C	current 1.0C(A) and constant voltage 3.65V,0.05C cut off,rest for 30min,discharge to 2.5V cut off with the current of 1.0C(A),rest for 30min,and thenstart  the  next  cycle,end  with  the capacity

			decrease to 80% of the initial capacity.The number of cycles is defined as the cycle life of the battery
6	End of Life Management	Capacity/Typical Capacity＜70%	During the use of the battery, when the endof life is exceeded, should stop use the battery.
