From the middle of that article, it might be 10 times the energy storage compared to previous development in thus field, but

"The battery has an energy density of 24 Wh/kg, meaning approximately 20 percent capacity compared to comparable lithium-ion batteries currently available. But since the weight of the vehicles can be greatly reduced, less energy will be required to drive an electric car, for example, and lower energy density also results in increased safety. "

Somehow I can't reconcile some basic arithmetic. How, for instance, would this work on a small two seater car with a body made of 100 kg of carbon fibre? How does it save quarter or half a ton of battery?
