  Advanced electrical conductors that outperform copper and aluminum can
revolutionize our lives, enabling billions of dollars in energy savings and
facilitating a transition to an electric mobility future. Nanocarbons (carbon
nanotubes and graphene) present a unique opportunity for developing advanced
conductors for electrical power, communications, electronics, and electric
machines for the aerospace, marine, and automotive industries. This paper
compiles the major research progress in the field of advanced nanocarbon-based
and metal-nanocarbon conductors. It also elucidates the competitiveness and
implications of advanced conductors with respect to conventional ones and
describes their materials science, properties, and characterization. Finally,
several areas of future research for advanced electrical conductors are
proposed.
