Structural Battery Composites: The Game-Changing Tech Turning Vehicles into Batteries
Researchers at Chalmers University in Sweden unveiled a carbon-fiber structural battery in 2024 with 30 Wh/kg energy density and stiffness similar to aluminum. The technology integrates energy storage into load-bearing parts, reducing vehicle weight and potentially increasing EV range by up to 70%. Airbus and automakers are testing structural battery composites in aircraft and electric vehicles. Prototypes remain below standard lithium-ion capacity but offer net performance gains.
