ABSTRACT:
1. A thermal battery comprising a plurality of cells, said cells comprising a metallic positive electrode and a metallic negative electrode spaced by a normally inactive electrolyte that becomes electrically active when heated, a combustible composition disposed between said cells and in contact therewith for supplying heat to the electrolyte, means for igniting said composition, said composition comprising an intimate mixture of a finely divided metal oxide and a finely divided metal capable of exothermically reacting with said metal oxide to form an electrically conductive metal oxide reaction product, thereby forming an electrically conductive ash when burned and providing an electrical connection between said cells.
