Abstract
Abstract A solid state ambient temperature cell having a thin layer of an alkali or alkaline earth metal as anode, a thin layer of a solid ionic conductive electrolyte and a thin cathode layer of a metal or metalloid which can accommodate anode cations in the crystalline structure thereof. Such metals or metalloids include bismuth, arsenic, antimony, lead, tin, selenium or tellurium. The cell is dischargeable at high rates and is rechargeable.
