摘要： Embodiments of the present disclosure pertain to electrodes that include a plurality of vertically aligned carbon nanotubes and a metal associated with the vertically aligned carbon nanotubes. The vertically aligned carbon nanotubes may be in the form of a graphene-carbon nanotube hybrid material that includes a graphene film covalently linked to the vertically aligned carbon nanotubes. The metal may become reversibly associated with the carbon nanotubes in situ during electrode operation and lack any dendrites or mossy aggregates. The metal may be in the form of a non-dendritic or non-mossy coating on surfaces of the vertically aligned carbon nanotubes. The metal may also be infiltrated within bundles of the vertically aligned carbon nanotubes. Additional embodiments pertain to energy storage devices that contain the electrodes of the present disclosure. Further embodiments pertain to methods of forming said electrodes by applying a metal to a plurality of vertically aligned carbon nanotubes.

摘要： Embodiments of the present disclosure pertain to methods of making electrically conductive materials by applying nanowires and graphene nanoribbons onto a surface to form a network layer with interconnected graphene nanoribbons and nanowires. In some embodiments, the methods include the following steps: (a) applying graphene nanoribbons onto a surface to form a graphene nanoribbon layer; (b) applying nanowires and graphene nanoribbons onto the graphene nanoribbon layer to form the network layer; and (c) optionally applying graphene nanoribbons onto the formed network layer to form a second graphene nanoribbon layer on the network layer. Additional embodiments of the present disclosure pertain to the formed electrically conductive materials and their use as components of electronic devices, such as energy storage devices. Further embodiments of the present disclosure pertain to electronic devices that contain the electrically conductive materials of the present disclosure.

摘要： Embodiments of the present disclosure pertain to electrodes for energy storage devices. The electrodes include a substrate from which extends bundles of carbon nanotubes. A metal, such as lithium, infiltrates the bundles, between the carbon nanotubes, to coat the surfaces of the carbon nanotubes. The bundled, metal-coated carbon nanotubes are covered with a layer of solid-electrolyte interphase that can be formed before the metal is inserted into the bundles by pretreating the bundles with an electrolyte bearing ions of the metal.
