1,101,286. Thermal batteries. UNITED STATES ATOMIC ENERGY COMMISSION. 13 July, 1966 [22 Sept., 1965], No. 31463/66. Heading HlB. A self-activating thermal battery, such as that shown in Fig. 2, comprises a cell having an anode 17 and a cathode collector 15 separated by a solid electrolyte 16, a thermally-actuable heat-generating substance or mixture of substances 25 for heating and melting the electrolyte upon reaching a predetermined temperature and a casing 11 enclosing the cell and heatgenerating substance(s) the casing including a pair of terminals 36 and 33 connected r e spectively to the cathode and anode. Fig. 2 shows two such cells connected together in series by a strap 22, the heat-generating substance(s) being placed between the two cells The electrolyte which may be a lithiumchloride-potassium chloride eutectic may be mixed with an inorganic binder and a depolarizer such as silver chromate. A nickel cathode may comprise the cathode collector and the anode may be formed of calcium pressed into a grid 19. The heat-generated substance is suitably in the form of a pellet of lead-tin solder and lithium. |
