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-co-polysulfur (PAS) materials of general formula (C2Sx)n wherein x is greater than 1 to about 100, n is equal to or greater than 2, and the sulfur chain is bound to the polymer by both terminal sulfur atoms. 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.
