Spanish Researchers Boost Carbon Nanotube Conductivity 17-Fold, Challenging Copper

Spanish researchers developed a carbon nanotube material with 17-fold higher conductivity, potentially replacing copper in EVs and aircraft. Lighter and stronger, it could extend range and reduce heat.

This breakthrough matters because it could drastically reduce the weight of electrical wiring in electric vehicles, drones, and aircraft, leading to longer range, better efficiency, and lower heat buildup. For consumers, this means more affordable and practical EVs and longer flight times for drones. For the industry, it offers a path to overcome a key bottleneck in electrification—weight—without sacrificing performance. If scaled, this carbon-based material could transform transportation, making it cleaner and more efficient.
