MENUFACTURE OF COUNTER ELECTRODES CONTAINING METAL/GRAPHENE COMPOSITES

摘要

The present invention relates to a method of manufacturing counter electrodes containing metal-graphene composites with metal nanoparticles. According to the present invention, metal nanoparticles are introduced onto the surface of a graphene electrode coated with graphene powder by using an electro-phoretic deposition method to form metal-graphene composites. A method of manufacturing counter electrodes containing metal-graphene composites with metal nanoparticles not only accurately controls the introduction of more uniform and dense metal nanoparticles compared to an existing physical or chemical method of introducing metal nanoparticles, but also achieves metal/graphene composites having more electrochemical properties compared to existing composites. Also, this method can be applied to graphene manufactured by various methods. This manufacturing process is easily carried out at low costs, thereby creating a high value-added product applied to various fields.
