Abstract:

The development of a chlorine trifluoride battery cathode in anhydrous hydrogen fluoride was continued in this program, and the feasibility of a lithium alloy anode in the same solvent was investigated. As a current collector for the cathode system, platinum was far superior to nickel, copper, aluminum, or boron carbide. The cathode process on platinum was characterized in some detail by voltammetric measurements on solutions of ClF3, Cl2, ClF, and mixtures thereof. It was concluded that the ClF3 system lacks adequate recharge capability for secondary battery applications, although it is a very active primary cathode. Lithium-aluminum and lithium-magnesium alloys ranging in formal compositions from Li9Al to LiAl2 and Li2Mg to LiMg2 were examined for chemical compatibility with a 1 M LiF-HF electrolyte and for anodic reactivity in the same medium. Lithium alloys thus show definite promise as anodes for reserve cells in HF. From the results an LiAlloy-ClF3 cell in HF is expected to perform as a high-energy, high-rate primary power source at low temperatures. Author
