    Many electric vehicles are powered by batteries that contain cobalt—a metal that carries high financial, environmental, and social costs.

    MIT researchers have now designed a battery material that could offer a more sustainable way to power electric cars. The new lithium-ion battery includes a cathode based on organic materials, instead of cobalt or nickel (another metal often used in lithium-ion batteries).

    In a new study, the researchers showed that this material, which...
