Abstract
The invention relates to an iron/lithium anode material for use in thermal batteries which comprises about 15% to 30% by weight lithium. Thermal batteries made from such anodes are also disclosed. The anode comprises particulate iron bound together by the surface tension of the lithium which wets the iron particles. A method is disclosed for the manufacture of the anode material which includes adding iron powder to a molten lithium and mixing to form a homogeneous mixture. The mixture is cooled to form an ingot and rolled into strips for fabrication into anode configurations.
