Studies of Components for Thermally Regenerative Electrochemical Systems

Abstract

Electrochemical studies on the reduction of AlCl 4- ion and the anodization of Al(O) in basic 1-methyl-3-ethylimidazolium chloride (ImCl) mixed with aluminum chloride (AlCl3) were carried out; a basic melt is one containing excess ImCl. It was not found possible to reduce the AlCl4 ion at temperatures as high as 250 deg C. The anodization of aluminum was found to be controlled by the diffusion of chloride ion to the electrode. The disposition of Li and Bi were studied at tungsten microelectrodes in LiCl-KCl eutectic molten salt at 450 deg C. Molten salts; ambient temperature chloroaluminates; lithium chloride - potassium chloride eutectic; electrochemistry.
