| Abstract Scope |
Growing demand for electrical energy and increasing need for high power grid systems necessitates development of new conductors for enhanced electrical and thermal conductivity. Ballistic electrical transport in carbon nanotubes (CNTs) is expected to improve the conductivity of the Cu matrix with additional CNT-enabled benefits that can enable low-weight, flexibility, and better thermal management. We demonstrate a novel technological platform to produce high-performance conductors that incorporates CNTs into the Cu matrix ― ultra-conductive metal composites (UCC), which promise significant technological and economic impact in all energy sectors, ranging from electrical vehicles to power grid. Here, we demonstrate that the prototype UCC composites exhibit improved electrical conductivity (by >5%), higher current carrying capacity (>10%), and higher mechanical strength (>10%) than the reference pure Cu. Furthermore, the compatibility of our fabrication methods with roll-to-roll processing facilitates scalability from laboratory prototypes to industrial-scale production of advanced copper conductors. |
