Copper's biggest rival yet? New carbon nanotube fibers could reshape wiring for EVs, drones and aircraft

Spanish researchers have demonstrated a scalable manufacturing process for carbon nanotube (CNT) fibers with electrical conductivity comparable to that of copper and aluminum. The result, published in Science, is a breakthrough for the future of electrification in aerospace, electric vehicles (EVs), drones and related applications, which require lightweight and high-strength electrical wiring.
