Title: Li.sub.2S batteries having high capacity, high loading, and high coulombic efficiency

Abstract

An electrochemical device includes a cathode containing graphene-wrapped Li.sub.2S nanoparticles. The graphene-wrapped Li.sub.2S nanoparticles are prepared by a method including heating lithium metal, and a carbon-sulfur source or a carbon source and a sulfur source in a sealed container at a temperature to produce lithium vapors, and vapors of the carbon-sulfur source or vapors of the carbon source and vapors of the sulfur source; and cooling the sealed container to produce the graphene-wrapped Li.sub.2S nanoparticles.
