Battery system for a portable electronic device

摘要

A battery system for a portable electronic device includes a thin wall can structure (12) for holding cathode and anode material and electrolyte defining a battery cell. Current is limited by a safety component (26) 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 (84) 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.
