A non-aqueous electrolyte for electric cells is an SO 2 -free solution, in an aprotic organic liquid which is a Lewis base, of an ionized addition complex of an inorganic halide which is a Lewis acid and an ionized inorganic salt the anion of which is an ion of the halogen of the Lewis acid; the Lewis acid being present in excess of the amount required to form the complex. Complex/Lewis acid pairs may be LiBF 4 /BF 3 , LiAlCl 4 /AlCl 3 , LiPF 6 /PF 6 and the aprotic solvent may be dimethoxymethane, 1,2 - dimethoxyethane, diglyme, tetrahydrofuran (THF), 2 - tetrahydrofurfuryloxytetrahydrofuran or N - methyl - 2 - pyrrolidone. The electrolytes may be used in primary cells, e.g. X|Li|LiBF 4 ,BF 3 ,THF|CuS, where X is a conductive material. CuO may also be used as cathodic material. |
