Fe-Li-Al ANODE COMPOSITE AND THERMAL BATTERY CONTAINING THE SAME

摘要

A solid anode composite material for use in thermal batteries that comprises about 65-85% by weight (about 34 to 40 atom percent) particulate iron, about 15-35% by weight (50 to 70 atom percent) lithium, and about 0.1-10% by weight (1.7 to 2.3 atom percent) aluminum. Lithium and Aluminum are only slightly or not alloyed with the particulate iron. The iron and/or the aluminum may be in the form of a powder. The aluminum may be in the form of lithium-aluminum alloy.
