Scientists have made a massless structural battery 10 times better than before. The battery cell performs well in structural and energy tests, with planned further improvements. Structural batteries reduce weight and could revolutionize electric cars and planes. In groundbreaking new research, scientists have made a structural battery 10 times better than in any previous experiment. ➡ You think science is badass. So do we. Let’s nerd out over it together. What’s a structural battery, and why is it such a big deal? The term refers to an energy storage device that can also bear weight as part of a structure—like if the studs in your home were all batteries, or if an electric fence also held up a wall. In the new paper , researchers from Chalmers University of Technology and KTH Royal Institute of Technology in Sweden reveal how their “massless” structural battery works. The main use case is for electric cars, where a literally massive amount of batteries take up a ton of room and don’t contribute to the actual structure of the car. In fact, these cars must be specially designed to carry the mass of the batteries. But what if the frame of the car […]
