✦ Synopsis

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 LiC104 and LiAsF, 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.

The gas-diffusion-electrode used in a Li-air cell has been studied in a unique homemade electrochemical cell. Three major obstacles for the development of a feasible Li-air system were discussed with a focus on the development of a functional gas-diffusion-electrode in non-aqueous electrolytes and t
