Patent ID: 6852446

Claim:
A non-aqueous electric current producing electrochemical cell comprising an anode and a cathode, an ionically permeable separator and a non-aqueous electrolyte comprising an ionically conducting salt in a non-aqueous medium, the ionically conducting salt corresponding to the formula: M + (Z*(J*) j (X*) x ) − , 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, C 1 -C 4 alkyl, alkoxide, halide and mixtures thereof, j is an integer from 2 to 12, and x is an integer from 0 to 4.
