On December 29, researchers from the University of Chicago and Argonne National Laboratory published findings in Nature Nanotechnology that flip battery science on its head. Single-crystal lithium-ion batteries—designed specifically to avoid the grain-boundary cracking that plagued older batteries—are failing anyway. But they're cracking for the exact opposite reason scientists expected.
