Main Performance

No.	Item	Requirements	Measuring Procedure
1	Rate discharge performance at25°C	Discharge capacity/nominal capacity×l00% A) 0.5C(A)>100% B) 1.0C (A)>98%	After standard charge and Ih rest, discharge to 2.5V cutoff with the current of 0.5 C (A), 1.0C (A), respectively. If the discharge capacity fails to meet the technical requirements, this test is allowed to be repeated three times
2	Discharge performance at different temperature	Discharge capacity/nominal capacity×100 % A) 55°C>95% (Cutoff 2.5V) B) -20°C>70% (Cutoff 2.0V)	Measure the initial capacity and state of the battery: A) after standard charge and 5h rest at 55°C, discharge to 2.5V cutoff with the current of 0.5C(A)； B) after standard charge at 25±2°C and 24h rest at -20°C±2°C, discharge to 2.0V cutoff with the current of 0.5C(A).
3	The capacity retention and recovery at 25°C	Capacity Retention ≥ nomi nal capacity×95 % Capacity Recovery ≥ nomi nal capacity×97 %	Measure the initial capacity and state of the battery, after standard charge and stored for 28 days, discharge to 2.5V cutoff with the current of 0.5C (A), calculate the remaining capacity the retention can be expressed as a percentage of nominal capacity. After standard charged and 30mins rest, calculate the discharging capacity (Ah), the recovery can be expressed as a percentage of nominal capacity. The recovery is measured with discharge current 0.5C (A) with 2.5V cut-off at (25±2) °C.
4	cycle life at 25 °C	>6000 cycle @0.5C/0.5C	Under the 300kgf clamp, after standard charged and 30mins rest, discharge to 2.5V cutoff with the current of 0.5C(A) at (25±2) °C, and then start the next cycle, end with the capacity decreasing to 80% of the

			initial capacity. The number of cycles is defined as the cycle life of the battery.
5	cycle life at 45 °C	>2500 cycle @0.5C/0.5C	Under the 300kgf clamp, after standard charged and 30mins rest, discharge to 2.5V cutoff with the current of 0.5C(A) at (45±2) °C, and then start the next cycle, end with the capacity decreasing to 80% of the initial capacity. The number of cycles is defined as the cycle life of the battery.
