Abstract:
A thermal battery comprising at least one cell, and preferably a plurality of stacked cells wherein each cell comprises an anode of a metal selected from the group consisting of alkali metals, alkaline earth metals and alloys thereof. Positioned against each cell anode is a homogeneous mixture, preferably in wafer form, of the electrolyte, depolarizer, and binder. The active depolarizer species of the present invention comprises iron pyrite (FeS. sub. 2) which provides a lower internal resistance to the battery and improves start times over conventional depolarizers used in thermal batteries.
