A new MIT battery material could offer a more sustainable way to power electric cars. Instead of cobalt or nickel, the new lithium-ion battery includes a cathode based on organic materials. In this image, lithium molecules are shown in glowing pink. Credit: MIT Chemists at MIT have created a battery cathode from organic materials, which could reduce the electric vehicle industry’s dependence on rare metals. Many electric vehicles are powered by batteries that contain cobalt — a metal that ca...
