NOVELTY - Preparing graphene/carbon nano-tube with three dimensional electrode structure comprises (i) using concentrated sulfuric acid and concentrated phosphoric acid mixture as solvent, taking potassium permanganate as oxidant, opening carbon nano-tube along the length direction to obtain carbon oxide nano-belt GONR, (ii) placing oxidized carbon nano ribbon, oxidized graphene and lithium iron phosphate in a polar solvent, and then mixing and performing ultrasonic treatment to make it uniformly dispersed to obtain mixed solution, then adding the mixed solution into hopper air spraying device, vacuum sucking and filtering the mixed solution gas through filter film, and (iii) after finishing spraying, covering the product with the filter membrane and drying, then separating the product and filter membrane, reducing the product hydrogen in the argon atmosphere high temperature, and then pressing the tablet to obtain the graphene/carbon nano-belt. USE - The structure is useful for energy storage battery electrode conductive network (claimed). ADVANTAGE - The structure blocks agglomeration of graphene between layers.
