Volvo's battery-infused car
In 2013, Volvo announced a potentially revolutionary approach to designing electric vehicles (EVs). It wanted to replace some of the steel body panels in its cars with carbon fiber composite materials that can store power like a battery.
The rechargeable panels would be composed of multiple layers of carbon fiber, which are insulated from each other by fiberglass inserts. The result is a structural component that can be charged like the battery.
