Abstract
Abstract Batteries wherein at least one of the anode and cathode is a conjugated backbone polymer and in which the electrolyte contains at least one sultone or sulfonate solvent. Preferred solvents such as propane sultone and butane sultone impart stability to the battery and permit the polymer, such as polyacetylene, to be highly oxidized or reduced without degradation.
