Using an in situ liquid transmission electron microscopy technique that can visualize chemical reactions occurring in liquid environments, researchers from the University of Illinois at Chicago and Argonne National Laboratory have discovered a new reason lithium-oxygen batteries—which promise up to five times more energy than the lithium-ion batteries that currently power electric vehicles and cell phones—tend to slow down and die after just a few charge/discharge cycles.
