By directly visualizing the uneven insertion of lithium ions into electrodes with well-defined crystal orientations, researchers learned why fast charging decreases battery lifespan and performance. The work could provide insights into better battery utilization and help investigations of the surface insertion reaction during fast charging. Read more »
