Abstract: Gas analysis and control methods for the operating atmospheres of traditional pressed pellet and research thin-film thermal batteries are discussed. Thermal modeling combined with tests on the operating gas atmospheres of vendor pressed pellet munitions thermal batteries clearly shows that many vendor pressed pellet thermal battery lifetimes can be increased by factors ranging from 1.5 to 3 by hydrogen [H2] gas removal even when using highly efficient microporous thermal insulation packages. An easily implemented method of H2 gas removal from vendor thermal batteries is proposed.
