Provided are a non-aqueous electrolyte battery and a non-aqueous electrolyte battery system that can be repeatedly charged and that have good storage characteristics in a high-temperature environment. A non-aqueous electrolyte battery of the present invention includes an electrode body in which a positive electrode and a negative electrode are laminated with a separator interposed therebetween, and a non-aqueous electrolyte. The negative electrode has a laminated body including a metal base layer that does not form an alloy with Li, and Al active layers respectively bonded to both faces of the metal base layer, or a laminated body including a metal base layer that is made of a metal selected from Ni, Ti, and Fe, or an alloy thereof, and an Al active layer bonded to the metal base layer. A Li&#x2014;Al alloy is formed at least on a surface side of each Al active layer.

A button-type alkaline battery in which an anodecontaining an anode active material and an alkaline electrolyte is disposed in a sealed space formed by sealing a cathode housingwith an anode sealing member, with a gasketbeing interposed between the cathode housingand the anode sealing member. The anode active material includes mercury-free zinc or a mercury-free zinc alloy. The button-type alkaline battery includes a metal layerthat is disposed between and in contact with the anode sealing memberand the anode. The metal layerincludes a base material containing zinc, and at least one metal M selected from the group consisting of indium, bismuth, and tin, with the metal M having segregated in the base material.
