SECONDARY BATTERY AND METHOD FOR FORMING ELECTRODE OF SECONDARY BATTERY
摘要
An object is to provide a secondary battery having excellent charge-discharge cycle characteristics. A secondary battery including an electrode containing silicon or a silicon compound is provided, in which the electrode is provided with a layer containing silicon or a silicon compound over a layer of a metal material; a mixed layer of the metal material and the silicon is provided between the metal material layer and the layer containing silicon or a silicon compound; the metal material has higher oxygen affinity than that of ions which give and receive electric charges in the secondary battery; and an oxide of the metal material does not have an insulating property. The ions which give and receive electric charges are alkali metal ions or alkaline earth metal ions.
