Abstract:

A summary of the development of a multishot thermal battery is presented. The battery is designed to power the ANPRC-77 radio for at least four ten-minute cycles. The cell of choice used a Ca anode, LiCl-KCl electrolyte and a CaCrO4 cathode depolarizer. The choice was based primarily on electrical performance and secondarily on prior experience with the system. Tests show that both the Mg anode and FeS2 cathode would also prove acceptable. Test regimens are described and test results detailed showing that the battery will meet electrical specifications when subjected to environmental preconditionings such as heat, cold, wind, vibration and dropping. A brief description of some of the tests which led to the choice of cell chemistry is included. A chronological description of design improvements is given, from the first working prototype which was capable of four cycles to the final version which is capable of at least five reliable cycles.
