A method of manufacturing an electrode for a super capacitor including crumpled graphene and an electrode for a supercapacitor prepared thereby

摘要

The present invention relates to a method for manufacturing an electrode for a supercapacitor containing crumpled graphene and an electrode for a supercapacitor manufactured thereby, and more specifically, a method for spraying a two-dimensional graphene oxide solution to a reducing agent solution containing a halogen element. As it is injected, a very small amount of two-dimensional graphene oxide solutions exiting through the spray nozzle is scattered in a reducing agent solution containing a halogen element, and particles are reduced in a different time in different solutions, resulting in increased hydrophobicity in the aqueous solution. Since shrinkage occurs, three-dimensional crumpled graphene particles can be produced in large quantities, and it is possible to solve the reduction in electrical and mechanical properties due to agglomeration and lamination that occurred in the conventional two-dimensional graphene manufacturing process. In addition, by mixing the three-dimensional crumpled graphene particles and carbon nanotubes and xanthan gum prepared by the above method in an appropriate composition ratio, it is possible to solve the problem occurring in the existing electrode due to the large volume and three-dimensional shape of the crumpled graphene. have.
