ABSTRACT:
Compounds are provided for use in an electrolyte comprising repeating unit selected from the group consisting of cyclic and heterocyclic species having y carbon atoms and z heteroatoms, X, and where y is 4, 5 or 6 and z is 0, 1 or 2. The heteroatom is selected from the group consisting of O, S and N. The repeating unit is further substituted by four to six pendant groups having the formula, (CHR.sub.1).sub.m O(CHR.sub.1 CHR.sub.1 O).sub.n Y, where the majority of pendant groups comprises at least two O and further,
