NOVELTY - A three-dimensional porous graphite preparation method involves mixing graphene oxide and alkaline material with water to obtain a composite dispersion. Polyurethane foam is immersed in the composite dispersion. The foam is removed, dried and calcined to obtain three-dimensional porous graphite. USE - Method for preparing three-dimensional porous graphite that is used in super-capacitor electrode material (claimed). ADVANTAGE - The method enables obtaining three-dimensional porous graphite with high porosity and large specific surface area, so that the electrode material has excellent electrochemical properties, and satisfying high energy density super-capacitor requirements.
