High-speed x-ray technology exposes hidden battery cell behavior

Cell manufacturers and vehicle integrators have always had to rely on simulations, destructive testing methods and indirect measurements. The Fraunhofer Institute for High-Speed Dynamics, Ernst-Mach-Institut (Fraunhofer EMI), has developed what it says is a unique high-speed x-ray system that makes dynamic processes inside large-format prismatic cells visible in real time for the first time.…
