ABSTRACT:
A thermal battery having improved performance under spin comprises an aligned stack of annular cell elements, including a combustible composition that forms a conductive ash on burning, forming a toroidal cell stack. A sheet of nonporous electrical insulating material such as mica tightly engages the outer peripheral surface of the cell stack and the central hole of the stack is filled with electrical insulating fuze material.
