Portion of a battery

A battery system for a portable electronic device includes a thin wall can structure for holding cathode and anode material and electrolyte defining a battery cell. Current is limited by a safety component integral with a cap assembly that seals the can structure and provides electrical and mechanical connection with a related battery pack engagement and holding arrangement which maintains the battery pack in an operative position in the electronic device. A finger groove is used to lift the battery pack from its operative position. A weakened wall in the finger groove functions as a safety vent and ruptures to release built-up pressure to prevent the battery pack from exploding.

Battery system for a portable electronic device

A battery pack for use with a cellular telephone device includes a flat battery cell assembly encased by a resin using low temperature molding techniques or injection molding techniques under low pressure. An interface assembly cap provides an electrical connection means between the cell assembly and the cellular telephone device with which it is used. The resin molded cell assembly accommodates a smaller physical size than preformed plastic battery packs without sacrificing relative available power density.
