a>:At room temperature, the battery

is charged at a constant current of 1/3C to 54.0V, and the battery is charged at a constant voltage to a

current of 0.05C；

b>:Rests for 30 min;

c>:Discharged at 1/3C to the cut-off voltage

42.0V at room temperature; d>:Rests for 30 min;

e>:Repeating steps of a) ~ d), until the discharge capacity reached the 70% of rated capacity, the number of cycles completed was defined as the battery

cycle life.
