Researchers at Argonne National Laboratory are using a new imaging technique to learn more about the process that causes lithium-ion batteries to degrade over time. Using coherent X-ray diffractive imaging at the DOE’s Advanced Photon Source facility, a team of researchers mapped the three-dimensional strain in individual nanoparticles within the electrodes of operating batteries. In… Read more »
