Study explores high-performance copper/graphene composite conductor for motors

https://phys.org/news/2024-06-explores-high-coppergraphene-composite-conductor.html

"scalable copper/graphene/plastic... high strength, electrical conductivity at room and elevated (>100°C) temperature... improved interfaces prepared by vacuum hot press sintering, cold-drawing, heat-treatment... wires' temperature resistance coefficient drastically reduced to 0.0035/°C, enabling low resistivity at higher temperatures... in-situ growth avoids carbon nanomaterial agglomeration, rare-earth oxide or carbide formation at interface, improving interfacial bonding... high power density EV motor winding wires"
