NOVELTY - Preparing nano-carbon aerogel film compirses using nano-carbon dispersion liquid to prepare nano-carbon aerogel film, passing through micro-nano foaming machine to form uniform micro-nano bubbles inside, coating foamed nano-carbon dispersion liquid on surface of the current collector substrate and quickly drying to obtain the nano-carbon aerogel film. USE - The nano-carbon aerogel film is used in supercapacitor, electromagnetic shielding material, flexible 3D electrode, and battery 3D current collector. ADVANTAGE - The method: is simple and economical; does not requires complex operations e.g. freeze-drying and supercritical drying; has strong operability. The nano-carbon aerogel film has high porosity (greater than 90%) and good compression resilience. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for nano-carbon aerogel film is prepared by above mentioned method.
