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 he in the form of a powder. The aluminum may be in the form of lithium-aluminum alloy.

摘要： The present invention is generally directed to a system for lithiating alloys. In accordance with one aspect of the invention, a method is provided for performing vapor deposition of a lithium alloy on a substrate comprising the steps of vaporizing a mass of lithium and controllably heating a lithium-soluble element, such as magnesium. The method further includes the step of disposing the lithium-soluble element in the lithium vapor, wherein the lithium vapor promotes the vaporization of the lithium-soluble element to create a combined vapor having intimately mixed constituencies from both the lithium and lithium-soluble element. Finally, the method includes the step of disposing a temperature controlled substrate in the combined vapor, whereby the combined vapor is deposited on the substrate. In accordance with another aspect of the invention, a method is provided for depositing lithium onto an aluminum element surface. This method includes the steps of vaporizing a mass of lithium and exposing the aluminum surface, at very stringent temperature, to the lithium vapor. This technique requires controllably heating an aluminum surface, so that the lithium vapor is deposited on this surface over a very precise temperature range (aluminum 570-590° C., lithium 525 to 585° C.) producing alloys whose lithium content does not exceed 5 wt % lithium.
