Abstract
Official abstract text for this publication.
A laminated battery, a battery element, and a laminate film enclosing the battery element, wherein the laminate film has a fused portion in which end portions are overlapped and an inner surface is fused, and the laminate film has a fused portion side surface in which a fused portion is formed, an opposite side surface opposed to the fused portion side surface, and a pair of main surfaces orthogonal to the fused portion side surface and the opposite side surface and having an area larger than the fused portion side surface and the opposite side surface, and the laminate film has an uneven shape on at least one of the fused portion side surface and the opposite side surface.
First claim
Opening claim text (preview).
What is claimed is: 1 . A laminated battery comprising: a battery element; and a laminate film that covers and seals the battery element, wherein: the laminate film includes a fused portion at which end portions are superposed on each other and inner surfaces are fused; the laminate film includes a fused portion side surface in which the fused portion is formed, an opposite side surface that faces the fused portion side surface, and a pair of main surfaces that is orthogonal to the fused portion side surface and the opposite side surface and that is larger in area than the fused portion side surface and the opposite side surface; and the laminate film includes a concave-convex shape in at least one of the fused portion side surface and the opposite side surface. 2 . The laminated battery according to claim 1 , wherein the laminate film includes the concave-convex shape in the opposite side surface. 3 . The laminated battery according to claim 1 , wherein the laminate film includes, in at least one of the fused portion side surface and the opposite side surface, the concave-convex shape in which a concave portion and a convex portion are repeated from one of the main surfaces toward the other one of the main surfaces. 4 . The laminated battery according to claim 1 , wherein the laminate film includes the concave-convex shape over an entire surface of at least one of the fused portion side surface and the opposite side surface.
