ShAPE needs six pounds graphene for 1 million lb of high efficiency copper

Andrea Star; Pacific Northwest National Laboratory

Keerti Kappagantula, a materials scientist at the Pacific Northwest National Laboratory holds copper wire with graphene additives that is 5% more conductive than the pure copper currently being used in electric motors.

Working with General Motors, researchers at the Pacific Northwest National Laboratory have discovered that a tiny bit of graphene can increase the conductivity of copper wire by 5%.

"That may seem like a small amount, but it can make a big difference in motor efficiency," the Washington state lab penned in an article on the findings. "Higher conductivity also means that less copper is needed f...
