NOVELTY - Method of preparing graphene hybridized cavernous capacitor desalting electrode, involves preparing electrode material by mixing nano-modified material and graphene oxide solution and freeze-drying the mixture, then preparing capacitive desalting electrode by mixing graphene hybrid sponge, acetylene black and polyvinyl alcohol aqueous solution, uniformly coating the mixture on graphite paper and drying at 80-100 degrees C to obtain the product. USE - The method is useful for preparing graphene hybridized cavernous capacitor desalting electrode. ADVANTAGE - The graphene hybrid is prepared using different nano graphene material, and the specific surface area and pore volume of graphene hybrid capacitor is controlled by regulating the type and content of the nanomodified material. The product is prepared simply under mild reaction condition.
