Abstract
An anode material capable of obtaining a high capacity and superior charge-discharge efficiency, and an anode and a battery using the anode material are provided. An anode includes an anode material including an active portion including at least one of silicon and tin as an element and a coating portion of a metal oxide arranged on a part of a surface of the active portion. The ratio of the coating portion to the active portion is within a range from 0.01 wt % to 10 wt % inclusive. Thereby, a high capacity and superior charge-discharge efficiency can be obtained.
