  • Electrical conductor made of graphene and/or carbon nanotubes having coated joints
    Patent number: 11875913
    Abstract: The present invention relates to an electrical conductor (1) having an electrically conductive material (2) comprising graphene and/or carbon nanotubes and a joint (3, 4), wherein a metal coating (6) is provided on the electrically conductive material (2) of the electrical conductor (1) at the joint (3, 4) for integrally joining the electrical conductor (1) to a metal conductor element, the metal coating (6) being in direct contact with the electrically conductive material (2), characterized in that the metal coating (6) of the joint (3, 4) comprises a metal that forms carbides in a boundary layer of the coating (6) by reaction of the metal of the coating (6) with the carbon of the electrically conductive material (2).
