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. 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...
