Cycling Test For Batteries

The charge–discharge cycling performance was investigated using a multichannel potentio-, galvanostat (TOSCAT-3100, TOYO system) in a temperature-controlled chamber.

Pouch cells were cycled once at a charging rate of 0.1 C and then at a discharging rate of 0.2 C in a voltage range of 2.5–4.25 V for the initial formation. A CV was applied until 0.05 C was achieved at 4.25 V, and 10 min holds were made at both 2.5 and 4.25 V. The CC mode of 0.5 C was adopted in a cutoff voltage range from 2.5 to 4.25 V versus Li+/Li for the cycle performance tests. For rate capability tests, the cells were cycled between 2.5 and 4.25 V with discharging rates ranging from 0.2 C to 2.0 C. The charging rate was kept constant at 0.1 C during the rate capability tests.5
