Method for manufacturing electrode, and method for manufacturing power storage device and power generation and storage device having the electrode |
摘要 |
The characteristics of a power storage device are improved and the lifetime of the power storage device is prolonged. An electrode is manufactured through the following steps: a step of forming an electrode film; a step of forming a damage layer by ion doping on the electrode film; and a step of providing a damage region between the damage layer and a surface. Alkali ion insertion and extraction can be performed by dipping of an electrode, in which the damage layer and the damage region are formed, in a solution containing an alkali ion. A space in which the volume of the electrode is expanded can be secured by the formation of the damage layer and the damage region. Note that another lithium may be used instead of an alkali metal. |
