Abstract
(EN)
A battery case according to an embodiment of the present invention for solving the problem accommodates an electrode assembly and is manufactured from a rigid metal foil. The battery case comprises: a lower case which includes a cup portion accommodating the electrode assembly, and has a terminal hole formed by perforating the outer wall thereof; and an upper case covering the lower case, wherein the transverse cross-section of the cup portion has a circular shape or a polygonal shape in which at least one of the internal angles is an obtuse angle or a reflex angle.
(FR)
Un boîtier de batterie selon un mode de réalisation de la présente invention pour résoudre le problème reçoit un ensemble d'électrodes et est fabriqué à partir d'une feuille métallique rigide. Le boîtier de batterie comprend : un boîtier inférieur qui comprend une partie coupelle accueillant l'ensemble d'électrodes, et a un trou de borne formé par perforation de la paroi externe de celui-ci ; et un boîtier supérieur recouvrant le boîtier inférieur, la section transversale de la partie coupelle ayant une forme circulaire ou une forme polygonale dans laquelle au moins l'un des angles internes est un angle obtus ou un angle réflexe.
