Abstract
Prismatic battery for a non circular spiral winding, having a metal container (1) of equal thickness formed by a rectangular base (15) and, perpendicular to the latter, by two small walls (12, 14) attached to said base (15), two large walls (11, 13) attached on the one hand to the small walls (12, 14) via narrow strips (21 to 24) of width 1.sub.1, on the other hand to the base (15) via narrow strips (25, 25a) of width 1.sub.2, said strips (21 to 24, 25 to 25a) being inclined towards the external faces of the large walls (11, 13) and having between them junction lines (26) from the four angles of the base (15).
