Secondary battery

Abstract

A secondary battery includes: a negative electrode; a positive electrode containing a p-type semiconductor material; and an isolation layer configured to isolate the negative electrode from the positive electrode and including a hole transmission member. The isolation layer is layered by being applied to at least one of the negative electrode and the positive electrode. Preferably, the hole transmission member contains α-alumina. Preferably, the isolation layer includes the same binding agent as the negative electrode or the positive electrode.
