Described herein is an electrochemical device including a cathode containing an electroactive material including LOor LO, wherein each L is independently selected from Li, Na, K, Be, Mg, Ca, and Al; the electroactive material is carbon-coated, metal-coated, metal oxide-coated, nano-sized, or doped; and the electroactive material is substantially free of transition metal catalyst.

High capacity lithium ion batteries having oxides, peroxides, or superoxides as cathode active material

An electrochemical device includes a cathode containing graphene-wrapped LiS nanoparticles. The graphene-wrapped LiS 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 LiS nanoparticles.
