  • Graphene macro-assembly-fullerene composite for electrical energy storage
    Patent number: 11715607
    Abstract: Disclosed here is a method for producing a graphene macro-assembly (GMA)-fullerene composite, comprising providing a mixture of graphene oxide and water, adding a hydroxylated fullerene to the mixture, and forming a gel of the hydroxylated fullerene and the mixture. Also described are a GMA-fullerene composite produced, an electrode comprising the GMA-fullerene composite, and a supercapacitor comprising the electrode.
    Type: Grant
    Filed: July 2, 2021
    Date of Patent: August 1, 2023
    Assignee: Lawrence Livermore National Security, LLC
    Inventors: Patrick G. Campbell, Monika M. Biener, Maira Raquel Ceron Hernandez

  • Graphene macro-assembly-fullerene composite for electrical energy storage
    Patent number: 10633255
    Abstract: Disclosed here is a method for producing a graphene macro-assembly (GMA)-fullerene composite, comprising providing a GMA comprising a three-dimensional network of graphene sheets crosslinked by covalent carbon bonds, and incorporating at least 20 wt. % of at least one fullerene compound into the GMA based on the initial weight of the GMA to obtain a GMA-fullerene composite. Also described are a GMA-fullerene composite produced, an electrode comprising the GMA-fullerene composite, and a supercapacitor comprising the electrode and optionally an organic or ionic liquid electrolyte in contact with the electrode.
