Electric cars could store energy in their carbon fiber bodies

You might not need a big, heavy battery to power an EV. Electric cars typically need larger, denser batteries if they're going to meet the range expectations of people used to gas-powered vehicles, but available space and weight limit the size of that battery. Researchers might have a solution: turn the very body of the car into a battery. They've conducted a study showing that carbon fiber shells could serve as battery electrodes. The trick is to optimize the size and orientation of the fibers so there's a good balance between stiffness and the electrochemical traits needed to store energy.
