| 主权项 | 1. A method for preparing an electrochemical device, comprising the steps of: charging an electrochemical device using an electrode active material having a gas generation plateau potential in a charging period to an extent exceeding the plateau potential during an initial charge cycle, the initial charge cycle being the first charge cycle after assembly of the electrochemical device; and degassing the electrochemical device after the plateau potential is exceeded in the initial charge cycle. | ||
