Electroactive high storage capacity polyacetylene-co-polysulfur materials and electrolytic cells containing same

摘要

The present invention relates to novel electroactive energy storing polyacetylene-copolysulfur (PAS) materials of general formula (C2Sx)n wherein x is greater than 1 to about 100, and n is equal to or greater than 2. This invention also relates to novel rechargeable electrochemical cells containing positive electrode materials comprised of said polyacetylene-co-polysulfur materials with improved storage capacity and cycle life at ambient and sub-ambient temperatures.
