Abstract
A powder comprises a plurality of carbon nanostructures, with at least a portion of the carbon nanostructures defining an internal cavity that contains metallic lithium, a lithium compound, or a lithium alloy comprising lithium. A method of forming the powder involves the electrolytic disintegration of a graphite electrode in a lithium-bearing molten salt to form the carbon nanostructures, and a step of removing salt from the nanoparticles without removing lithium. A lithium battery anode comprising an anode comprising the powder as a layer on an electrically conductive substrate.
