摘要
A composite material of carbon-coated graphene oxide, its preparation method and application are provided. The method for preparing the composite material comprises the following steps: obtaining graphene oxide; mixing the said graphene oxide and the source of organic carbon according to the mass ratio of 1-10:1 in water to form a mixed solution; making the mixed solution react hydrothermally under the condition of 100ˆ¼250 °C, cooling, solid-liquid separating, washing, and drying to attain the composite material. The advantages of the preparation method are simple process, low energy consumption, low cost, no pollution and suitable for industrial production. The advantages of composite material are stable structural performance, high electric conductivity. Lithium ion battery and/or capacitor have/has high power density while the composite material is used to prepare the anode material of lithium ion battery and/or capacitor.
