of said quaternary ammonium halide to said aluminum halide
being not larger than 1:1.
20. A method for the electrodeposition of aluminum,
comprising the step of subjecting a non-aqueous electrolyte
comprising, in combination, an aluminum halide and a
quaternary ammonium halide in a non-aqueous solvent to
electrodepostion, thereby depositing aluminum on a cathode,
wherein said non-aqueous solvent is an organic compound
having a donor number of not larger than 5, and a molar ratio
of said quaternary ammonium halide to said aluminum halide
being not larger than 1:1.
34. A non-aqueous electrolyte comprising an aluminum
halide and a quaternary ammonium halide in a non-aqueous
solvent selected from the group consisting of 1,2-
dichlorobenzene, 1,3-dichlorobenzene and mixtures thereof.
35. A method for the electrodeposition of aluminum
comprising the step of subjecting a non-aqueous electrolyte
including an aluminum halide and a quaternary ammonium halide
in a non-aqueous solvent selected from the group consisting of
1,2-dichlorobenzene, 1,3-dichlorobenzene and mixtures thereof
[sic, to a cathode].
The sole prior art reference of record relied upon by the
