Lithium-Aluminum Alloy Electrodes in Lithium Chlorate

摘要

To prevent lithium dendrite growth during cycling of Li electrodes in molten LiClO3 at 140 C, a Li-Al electrode in cells of the type Li/LiClO3/liAl has been investigated. Two discharge plateaus, one about 0.42V and the other about 0.20V versus a lithium wire, were obtained. No lithium dendrites were observed. Continued cycling caused the lithium-aluminum electrode to break down to particles or grains. The corrosion of isolated Al grains during operation of a Li-Al electrode was confirmed using atomic absorption spectrophotometer (AA) analysis on a white precipitate formed where the alloy electrode had been.
