Abstract: The nonaqueous electrolyte battery has good storage characteristics in a high temperature environment. The inventive nonaqueous electrolyte battery includes: an electrode body that is obtained by laminating a positive electrode and a negative electrode with a separator in between; a nonaqueous electrolyte solution that contains a lithium salt and an organic solvent. The inventive nonaqueous electrolyte battery is characterized in that the positive electrode includes a lithium-containing layered nickel oxide that contains 50% by mole or more of Ni relative to Li; that the negative electrode includes a laminate that contains a metal base layer which is not alloyed with Li, and an Al active layer that is bonded to one surface or both surfaces of the metal base layer; and that a Li—Al alloy is formed on at least the surface side of the Al active layer.

Abstract: 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—Al alloy is formed at least on a surface side of each Al active layer.

Abstract: Provided are a non-aqueous electrolyte battery that exhibits favorable load characteristics at low temperatures after being stored at a high temperature, and a method for manufacturing the non-aqueous electrolyte battery. A non-aqueous electrolyte battery of the present invention includes a negative electrode, a positive electrode, and a non-aqueous electrolyte.
