Résumé

A study has been carried out of the different processes — chemical corrosion, solid state diffusion and mechanical disintegration — affecting aluminium-lithium electrodes formed either by an electrochemical or a pyrometallurgical process. Cycling operations present similar limitations with aprotic electrolytes using dioxolane and propylene carbonate as solvents, and LiClO4 and LiAsF6 as solutes. Preliminary tests conducted with compressed LiAl powder electrodes show the existence of other processes responsible for the degradation of these electrodes during cycling.
