Car Doors And Hoods Could Store Power, Cutting Battery Weight and Increasing Hybrids' Range

• Rebecca Boyle via

Future hybrid cars won’t just have powerful batteries — they will be storing energy in their doors, hoods and roofs. Car parts could serve as capacitors, which would allow for smaller and more lightweight batteries, thus increasing a hybrid’s range.

Researchers at Imperial College London are working on lightweight auto body components that also store electricity, reports the New York Times. The car frames would be made of plastic composites reinforced with carbon fiber. The resin that binds the carbon fibers is doped with lithium ions, the Times reports — this allows the car’s frame to store electricity.

One of the biggest obstacles to increasing a hybrid car’s range is the size and weight of the battery. More powerful batteries can power a car for a longer distance, but they also weigh more, and this saps more energy, counteracting the power increase. High-efficiency lightweight batteries are a ripe field of study. But this research, which also involves automaker Volvo, takes energy storage out of the battery and directly into the car.
