Abstract
A method for improving cycling performance of a battery includes, in a first stage, charging the battery with a first-stage current until a voltage of the battery reaches a first-stage voltage value and in a second stage, charging the battery with a second-stage current until the voltage of the battery reaches a second-stage voltage value. The second-stage voltage value is greater than the first-stage voltage value, and the second-stage current is less than the first-stage current.
