Bipolar electrode, bipolar battery, and method of producing recycled material

Abstract

A bipolar electrode includes, in sequence in a plane-perpendicular direction: a positive electrode composite material layer; a positive electrode current collector foil; an interposition film; a negative electrode current collector foil; and a negative electrode composite material layer. Each of the positive electrode current collector foil and the negative electrode current collector foil is attached to the interposition film. The positive electrode composite material layer is attached to the positive electrode current collector foil. The negative electrode composite material layer is attached to the negative electrode current collector foil. The interposition film has conductivity. The bipolar electrode is configured such that at least one of the positive electrode current collector foil and the negative electrode current collector foil is separated from the interposition film before the interposition film is broken when the interposition film is stretched in an in-plane direction.
