A thermal cell (10) comprises a layered stack composed of a cathode (11), an electrolyte (12) and an anode (13). The cathode (11) is formed by a pellet (2) of iron disulphide and/or calcium chromate. The electrolyte (12) is a compressed pellet (3) of active material together with an inert binder, the active material being a eutectic mixture of lithium and potassium chlorides or a mixture, which may be eutectic, of lithium bromide, chloride and fluoride, or a eutectic mixture of lithium bromide, chloride, fluoride and iodide. The anode is formed by a nickel or iron cup (5) containing a body (4) of sintered nickel plaque impregnated with an anode reactive material which may be lithium or lithium alloys which are molten at the cell operating temperature. The cell (10) may be one of a set housed together with a pellet of pyrotechnic material (26) within a thermally insulated container (21) and electrically interconnected to form a battery (20). <IMAGE> |
