New sulfur-based polyesters have been synthesized. When these polymers are combined with electrolyte salts, such polymer electrolytes have shown excellent electrochemical oxidation stability in lithium battery cells. Their stability along with their excellent ionic transport properties make them especially suitable as electrolytes in high energy density lithium battery cells.
