    Abstract: In this non-aqueous electrolyte secondary battery, a positive terminal and a negative terminal extend in a first direction, protrude from a laminated cell stack, and are provided so that a center line is interposed therebetwen, the center line passing through a midpoint of both ends of the laminated cell stack in a second direction orthogonal to the first direction and extending in the first direction when the laminated cell stack is seen in plan view, and a first terminal with higher heat dissipation efficiency among the positive terminal and the negative terminal is provided in a location closer to the center line than a location of a second terminal with lower heat dissipation efficiency among the positive terminal and the negative terminal.

    Abstract: A non-aqueous electrolytic liquid secondary battery wherein a potential of a metal layer in an exterior body is kept high, and corrosion can be suppressed, wherein an average thickness t1 of a first part of an exterior body covering a first side surface where a negative and a positive electrode terminal of a power generation element exist is different from an average thickness t2 of a second part of the exterior body covering a second side surface that intersects the first. In plan view of the power generation element from a lamination direction, in a second direction orthogonal to a first direction in which the electrode terminals extend, the relationship of t1 t2 is satisfied when the width of the negative electrode is smaller than the positive.
