An electrolyte for use in an electrochemical cell is disclosed of the alkali metal-aluminium-halide type. The electrolyte has a melting point below 140 DEG C. at atmospheric pressure and conforms with the stoichiometric product MAlX4 wherein M represents lithium cations, a mixture of lithium and potassium cations or a mixture of sodium and potassium cations; and X represents a mixture of chloride and fluoride anions. A method of reducing the melting point of a sodium-aluminium-chloride or lithium-aluminium-chloride electrolyte by doping it with a potassium fluoride, sodium fluoride, or lithium fluoride, to obtain said electrolyte with a melting point below 140 DEG C. is disclosed, as are various electrochemical cells employing the product electrolyte. |
