  • Method of producing graphene
    Patent number: 10865488
    Abstract: A method of producing graphene sheets comprising the steps of, (a) forming a carbonaceous powder by electrochemical erosion of a graphite electrode in a molten salt comprising hydrogen ions, (b) recovering the resulting carbonaceous powder from the molten salt liquid, and (c) thermally treating the carbonaceous powder by heating the carbonaceous powder in a non-oxidising atmosphere to produce a thermally treated powder comprising graphene sheets.
    Type: Grant
    Filed: October 28, 2019
    Date of Patent: December 15, 2020
    Assignee: Cambridge Enterprise Limited
    Inventors: Derek Fray, Ali Kamali

  • POWDER COMPRISING CARBON NANOSTRUCTURES AND ITS METHOD OF PRODUCTION
    Publication number: 20150056513
    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.
