Abstract
A supercapacitor electrode mechanism comprising an electrically conductive, porous substrate, having one or more metallic oxides deposited on a first surface and a chemically reduced graphene oxide deposited on a second surface, to thereby provide an electrical double layer associated with the substrate. The substrate may be carbon paper or a similar substance. The layers of the supercapacitor are optionally rolled into an approximately cylindrical structure.
Claims10
A method for fabricating a supercapacitor, the method comprising:
- providing an electrically conductive substrate, having spaced apart first and second surfaces;
- providing a layer of metal oxides, including at least one of MnO2 and Co3O4, contiguous to the first substrate surface;
- and
- providing a layer of chemically reduced graphene oxide (rGO) contiguous to the second substrate surface, to thereby provide an electrical double layer associated with the substrate.
