Co-electrophoretic deposition of Co3O4 and graphene nanoplates for supercapacitor electrode

•Fabrication of Co3O4-graphene nano-composites for supercapacitor, is proposed.•A co-deposition of Co3O4-graphene via elctrophoretic deposition method is proposed.•The co-deposition with different morphology and size in EPD process is considered. In this work, we used the electrophoretic deposition...
