Daily Mail: Volvo is developing an electric car whose rechargeable battery is to be integrated into the car’s body. The car’s doors, roof, and hood would be replaced by a composite blend of carbon fibers and polymer resin, which would store and charge more energy faster than conventional batteries and reduce the car’s weight by as much as 15%. If successful, the technology could also be applied to other devices, such as mobile phones and laptops, to make them smaller, lighter, and more portable.
