Abstract

Official abstract text for this publication.

A lithium secondary battery includes: a positive electrode film into which lithium ions can be inserted and from which lithium ions can be eliminated; a negative electrode film that is any one of a negative electrode film of lithium, a negative electrode film made of a material capable of forming an alloy with lithium, and a negative electrode film into which lithium ions can be inserted and from which lithium ions can be eliminated; a transparent and solid electrolyte film that is located between the positive electrode film and the negative electrode film and has lithium ion conductivity; and two transparent substrates sandwiching, between transparent conductive films formed on respective surfaces of the transparent substrates, the positive electrode film and the negative electrode film having the electrolyte film therebetween.

1 . A lithium secondary battery comprising: a positive electrode film into which lithium ions can be inserted and from which lithium ions can be eliminated; a negative electrode film that is any one of a negative electrode film of lithium, a negative electrode film made of a material capable of forming an alloy with lithium, and a negative electrode film into which lithium ions can be inserted and from which lithium ions can be eliminated; a transparent and solid electrolyte film that is located between the positive electrode film and the negative electrode film and has lithium ion conductivity; and two transparent substrates sandwiching, between transparent conductive films formed on respective surfaces of the transparent substrates, the positive electrode film and the negative electrode film having the electrolyte film therebetween. 2 . The lithium secondary battery according to claim 1 , wherein the electrolyte film contains a polymer. 3 . The lithium secondary battery according to claim 2 , wherein the electrolyte film further contains aluminum oxide. 4 . A method for manufacturing a lithium secondary battery, the method comprising: a step of forming a transparent conductive film on a surface of a first transparent substrate and forming a transparent conductive film on a surface of a second transparent substrate; a step of preparing a transparent and solid electrolyte film having lithium ion conductivity; a step of forming, on one surface of the electrolyte film, a positive electrode film into which lithium ions can be inserted and from which lithium ions can be eliminated; a step of forming, on the other surface of the electrolyte film, a negative electrode film that is any one of a negative electrode film of lithium, a negative electrode film made of a material capable of forming an alloy with lithium, and a negative electrode film into which lithium ions can be inserted and from which lithium ions can be eliminated; and a step of superimposing the transparent conductive film of the first transparent substrate on a surface of the positive electrode film and superimposing the transparent conductive film of the second transparent substrate on a surface of the negative electrode film.
