This invention includes a tapered electrode assembly for providing a crumple zone in a rechargeable cell. The taper, which may be curvilinear, angular or piecewise linear, allows a void to exist between the corner of the metal can and the electrode assembly. This "crumple zone" prevents any external damage to the can from damaging the internal electrode assembly. The invention facilitates passage of common OEM drop testing without compromising cell performance or energy storage capacity. The invention increases the reliability of the cell by allowing the cell to resist external impacts.
