Abstract

One embodiment includes an electrical cell that includes a flat housing, at least one electrode and an electrically and heat conductive tab coupled to the electrode and extending through the housing for electrically and thermally coupling to a collector panel, the tab being capable of conducting both current and a substantial amount of heat out of the housing to a temperature control system. The cells may be stacked to form a battery having a temperature panel interfaced to the temperature control system by a thermal interface. The battery may propel an electrically-powered vehicle or the like.
