Compositions, layerings, electrodes and methods for making

摘要

There is a composition comprising 1 to 17.5 wt. % ionomer composition comprising hydrocarbon ionomer and 50 to 99 wt. % carbon-sulfur composite made from carbon powder having a surface area of about 50 to 4,000 square meters per gram and a pore volume of about 0.5 to 6 cubic centimeters per gram. The composite has 5 to 95 wt. % sulfur compound. There is also a layering comprising a plurality of coatings. Respective coatings in the plurality of coatings comprise respective compositions. The respective coatings comprise at least one ionomer composition comprising hydrocarbon ionomer and at least one carbon-sulfur composite of carbon powder and sulfur compound. There are also electrodes comprising the composition or layering and methods of using such in cells.
