Abstract
A secondary battery includes: a first oxide semiconductor having a first conductivity type; a first charging layer disposed on the first oxide semiconductor layer, and composed by including a first insulating material and a second oxide semiconductor having the first conductivity type; a second charging layer disposed on the first charging layer; a third oxide semiconductor layer having a second conductivity type disposed on the second charging layer; and a hydroxide layer disposed between the first charging layer and the third oxide semiconductor layer, and containing a hydroxide of a metal constituting the third oxide semiconductor layer. The highly reliable secondary battery is capable of improving an energy density and increasing battery characteristics (electricity accumulation capacity).
