Abstract: A method for preparing a graphene-nanosheets based concrete additive is disclosed. The method comprises mixing Polycarboxylate ether A (PCE-A) to a retarder - based salt solution to obtain a retarder-based Polycarboxylate ether A solution. In the next step, a retarder based PCE solution is obtained by adding Polycarboxylate ether B to the retarder based Polycarboxylate ether A solution to which graphene nanosheets are added. Further, an air entrainment agent is added to graphene nanosheets based PCE solution and further mixed to obtain the graphene nanosheets based concrete additive.

Abstract: 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.
