摘要: Embodiments of the present disclosure pertain to electrodes that include a plurality of vertically aligned carbon nanotubes and sulfur associated with the vertically aligned carbon nanotubes. The electrodes may also include a substrate (e.g., a porous nickel foam) and a carbon layer (e.g., graphene film). In some embodiments, the carbon layer may be positioned between the substrate and the vertically aligned carbon nanotubes. In some embodiments, the electrodes may be in the form of a graphene-carbon nanotube hybrid material that includes: a graphene film; and vertically aligned carbon nanotubes covalently linked to the graphene film. In some embodiments, the electrodes of the present disclosure serve as cathodes or anodes in an energy storage device. Additional embodiments pertain to energy storage devices that contain the electrodes of the present disclosure. Further embodiments of the present disclosure pertain to methods of making the electrodes and incorporating them into energy storage devices.
