CA 2463456

A battery can (1) of a battery accommodating power generating elements comprising an electrode group (41) and an electrolyte. A plurality of ridges (3) which have a bottomed cylindrical shape, and are swollen from an inner surface (2) of the can so that the thickness of the wall of the can is increased. The ridges are inclined at two angles to the axial direction on both sides of the cylinder axis (S), and the ridges (3) join and intersect each other via intersections (9) thereby forming a lattice.

L'invention concerne le boîtier (1) d'une batterie dans laquelle sont logées des éléments générant de l'énergie et comportant un groupe électrode (41) et un électrolyte. Une pluralité de nervures (3) de forme inférieure cylindrique forment un renflement à partir de la face intérieure (2) du boîtier, augmentant ainsi l'épaisseur de la paroi dudit boîtier. Ces nervures (3) sont inclinées pour former deux angles par rapport à l'axe sur les deux côtés de l'axe (S) du cylindre et elles se rejoignent et se croisent à des intersections (9) pour constituer ainsi une grille.
