Abstract
Provided is a method capable of producing, with excellent operability, a laminated electrode assembly which is stably restrained. The method for producing a laminated electrode assembly disclosed herein includes a step of preparing a laminate in which a plurality of positive electrode sheets and a plurality of negative electrode sheets are alternately laminated, and a separator is interposed between each positive electrode sheet and each negative electrode sheet; a step of enveloping, with a heat shrinkable film, four faces of the laminate including a pair of main faces perpendicular to a lamination direction of the laminate and facing each other, and a pair of end faces parallel to the lamination direction of the laminate and facing each other; and a step of heating the pair of end faces while sandwiching the pair of main faces with a cooling plate to thermally shrink the heat shrinkable film on the pair of end faces.
