Abstract

The subject invention provides a battery pouch or container which is highly resistant to shorting. This electrical protection is produced by a folding of the packaging laminate such that the cut edge of the laminate is physically removed and electrically protected from the electrode tab which protrudes from the battery pouch. In one embodiment, the cut edge of the film is folded away from the electrode tab. In a preferred embodiment, the laminar packaging material includes a convex flap of material where the electrode traverses the package. The convex flap is folded away from the electrode tab without wrinkling or distorting the pouch shape. In an alternate embodiment, an intervening layer of insulative material is placed between the cut edge and the electrode tab.
