Can a life prediction model simulate capacity recovery in lithium-ion batteries?

This work includes a life prediction model to simulate capacity recovery. The unavoidable long-term storage after production can result in capacity and power fading in commercial lithium-ion batteries. Remarkably, the decreased capacity is partially and gradually recovered when the stored cells are cycled again, known as capacity recovery.

What is a capacity recovery cycle?

Therefore, we use a capacity recovery cycle, which consists of four cycles. The first cycle discharges and charges the cell at a nominal 0.2 C discharge and a nominal 0.1 C charge current. This cycle sets the cell in a reproducible condition.

How do you calculate a recovery time constant?

The recovered capacity was calculated using Equation (3) by the subtraction of the cell capacity of the fourth cycle after its second discharge and the cell capacity of the second cycle. In order to estimate a recovery time constant, the recovered capacity was modeled using Equation (5).
