摘要：[Object] Provided is a means that can improve the output characteristics, underlow temperature conditions, of a non-aqueous electrolyte secondary battery thatcontains a spinel type lithium manganese composite oxide as a positive electrode activesubstance and is obtained by encasing a power generating element inside an outer casingformed of a laminate film. [Solving Means] Disclosed is a non-aqueous electrolytesecondary battery obtained by encasing, inside an outer casing formed of a laminate film,a power generating element containing a positive electrode obtained by forming, on thesurface of a positive electrode current collector, a positive electrode active substancelayer containing a positive electrode active substance, a negative electrode obtained byforming, on the surface of a negative electrode current collector, a negative electrodeactive substance layer containing a negative electrode active substance, and a separator,wherein the positive electrode active substance is made to contain a spinel typemanganese positive electrode active substance and a lithium nickel-based compositeoxide and the mixing ratio of the lithium nickel-based composite oxide is 30 to 70% byweight relative to the total 100% by weight of the spinel type manganese positive

electrode active substance and the lithium nickel-based composite oxide.
