Abstract
The present disclosure provides a method for manufacturing an angular battery having improved insertability of an electrode body. According to the present disclosure, there is provided a method for manufacturing an angular battery including a battery case that has a rectangular bottom surface and a pair of long side surfaces having, as one side thereof, a long side of the rectangular bottom surface and facing each other, and an electrode body that is accommodated in the battery case and wide surfaces facing the long side surfaces. The manufacturing method includes a preparation step of preparing a first member having substantially U-shaped end faces including the bottom surface and the pair of long side surfaces extending from the bottom surface, and a second member and a third member that are to be joined to respective end faces of the first member and constitute short side surfaces; a sandwiching step of sandwiching the wide surfaces of the battery body between the pair of long side surfaces of the first member; and a joining step of joining the second and third members to the respective end faces of the first member in a state in which the electrode body is sandwiched by the pair of long side surfaces.
