ABSTRACT:
A non-aqueous electric current producing electrochemical cell is provided comprising an anode and a cathode, an ionically permeable separator interposed between the anode and the cathode, and a non-aqueous electrolyte, the electrolyte comprising an ionically conducting salt in a non-aqueous medium, the ionically conducting salt corresponding to the formula:in-line-formulae description="In-line Formulae" end="lead"?M+(Z*(J*)j(X*)x)−,in-line-formulae description="In-line Formulae" end="tail"?wherein:M is a lithium atom,Z* is an anion group containing two or more Lewis basic sites and comprising less than 50 atoms not including hydrogen atoms,J* independently each occurance is a Lewis acid coordinated to at least one Lewis basic site of Z*, and optionally two or more such J* groups may be joined together in a moiety having multiple Lewis acidic functionality,X* independently each occurrence is selected from the group consisting of H, C1-C4alkyl, alkoxide, halide and mixtures thereof,j is an integer from 2 to 12, andx is an integer from 0 to 4.
