PROBLEM TO BE SOLVED: To increase the charge/discharge cycle stability of a molten salt electrolyte lithium ion battery.SOLUTION: A battery according to the present invention comprises: a positive electrode; a negative electrode; and an electrolyte. The positive electrode includes a positive electrode active material, and has a positive electrode area and a positive electrode capacity. The negative electrode includes a negative electrode active material, and has a negative electrode area and a negative electrode capacity. The battery has an electrode areal ratio which is equal to the quotient of division of the positive electrode area by the negative electrode area, and an electrode capacity ratio which is equal to the quotient of division of the positive electrode capacity by the negative electrode capacity. The electrode areal ratio is at least one, and the electrode capacity ratio is at least one.SELECTED DRAWING: None 【課題】溶融塩電解質リチウムイオン電池の充放電サイクル安定性を向上させる。【解決手段】本発明に係る電池は正極と負極と電解質とを有する。正極は正極活物質から成り、正極面積と正極容量とを有する。負極は負極活物質から成り、負極面積と負極容量とを有する。電池は、正極面積を負極面積で除したものに等しい電極面積比と、正極容量を負極容量で除したものに等しい電極容量比とを有する。電極面積比は少なくとも１、電極容量比は少なくとも１である。【選択図】なし
