A method for preparing a dry electrode is disclosed. The method comprises mixing of nanoparticles and graphene nanosheets in powder form to obtain a nanocomposite. The nanocomposite is compressed to obtain a compacted material, which is rolled to obtain a three dimensional graphene architecture framework (3D-GAF) active film. The 3D-GAF active film is laminated on a current collector to obtain a three dimensional graphene architecture framework dry electrode for next generation energy storage devices.
