    摘要: A method for making sulfur-graphene composite material is disclosed. In the method, a dispersed solution including a solvent and a plurality of graphene sheets dispersed in the solvent is provided. A sulfur-source chemical compound is dissolved into the dispersed solution to form a mixture. A reactant, according to the sulfur-source chemical compound, is introduced to the mixture. Elemental sulfur is produced on a surface of the plurality of graphene sheets due to a redox reaction between the sulfur-source chemical compound and the reactant, to achieve the sulfur-graphene composite material. The sulfur-graphene composite material is separated from the solvent.

    摘要: In the method for making graphene, an electrolyte solution is formed by dissolving an electrolyte lithium salt in an organic solvent. Lithium ions are separated out from the electrolyte lithium salt in the electrolyte solution. Metal lithium and graphite are disposed in the electrolyte solution, and the metal lithium and the graphite are in contact with each other. In the electrolyte solution, lithium ions and organic solvent molecules jointly insert between adjacent layers of the graphite to form a graphite intercalation compound. The graphene is peeled off from the graphite intercalation compound.

    摘要: The present disclosure relates to a method for making an electrode material of lithium-ion batteries. In the method, a carbon source compound is dissolved into a solvent to form a liquid phase solution. A number of titanium dioxide particles are provided and are dispersed into the liquid phase solution. The carbon source compound is pyrolyzed, thereby forming a number of carbon coating titanium dioxide particles. A lithium source solution is provided. The lithium source solution and the carbon coating titanium dioxide particles are mixed, according to a molar ratio in a range from about 4:5 to about 9:10, of lithium element to titanium element, thereby forming a sol. The sol is spray dried to form a number of precursor particles. The precursor particles are heated to form a lithium titanate composite electrode material.
