Abstract : In accordance with this invention, it has been found that highly efficient, lightweight, thermally activated power sources can be fabricated by utilizing a transition metal chloride such as cupric chloride, ferric chloride, or molybdenum chloride as the cathode; and a lithium metal or lithium-aluminum or lithium-silicon alloy as the anode in combination with an alkali metal tetrachloroaluminate solid electrolyte. The power source may comprise a single cell or a stack of individual cells. A typical cell is a three layered pellet composed of a lithium alloy anode, a separating alkali metal tetrachloroaluminate solid electrolyte sandwiched between the anode and a cathode which, in turn, is composed of a mixture of the transition metal chloride and graphite. The cell is totally inert until raised to its operating temperature by any conventional heating means.
