Abstract

See full text

A method of making a composition, comprising: (1) oxidizing graphite to graphite oxide using at least one sulfur-containing reagent, (2) exfoliating the graphite oxide to form graphene sheets, and (3) blending the graphene sheets with elemental sulfur and/or at least one organosulfur compound, wherein the graphene sheets comprise at least about 1 weight percent sulfur. The composition may be made into an electrode that may be used in batteries, including lithium sulfur batteries.
