6 FAQs about [Battery life curve]

How do voltage-capacity discharge curves affect battery life?

In Fig. 1 (a), (b), and (c), from the 10th cycle to the 100th cycle the voltage–capacity discharge curves shift to the left. Upon examining the voltage-capacity discharge curves of the 100th and 10th cycles, it appears that the larger the shift between the two curves, the shorter the battery's cycle life.
