Abstract

A new battery design is provided. The design is applicable to rectangular prismatic shaped batteries, and improves the reliability through the shaping of the batteries to reduce stresses on the electrochemical cells therein, and the flexible packaging encapsulating the electrochemical cell.At least one chamfer (22) is provided between adjacent planar sides of the cell to create a space between each chamfer of the cell and the planar sides and intersecting edges of the container of sufficient size to accommodate folded material at the corners of the folded down sealing flange.
