Auteurs : RBID : ISTEX:10800_1992_Article_BF01023814.pdfAbstract
Exploratory work on the anodic dissolution behaviour of aluminium and aluminium binary alloys in electrolytes in non-aqueous organic solvents is reported. Commonly used electrolytes for non-aqueous battery systems were selected on the basis of their conductivities and activities for anodic dissolution of Al and Al-alloy anodes. It is found that Al−In alloy electrodes exhibit an exceptionally active anodic dissolution behaviour in a 1 M solution of AlCl3 in anhydrous acetonitrile. The steady-state Tafel polarization plots for dissolution of pure Al, Al−Sn, Al−Ga and Al−In alloy anodes are compared, and a.c. impedance spectra for an Al−In alloy anode in 1 M solution of AlCl3 in CH3CN are evaluated and discussed. The In component, like Ga or Hg, interferes with passivation of Al during its anodic dissolution and thus promotes an “active” condition on the metal surface leading to relatively high anodic dissolution current-densities at substantially negative electrode potentials.
