Using an advanced, new microscopy technique that can visualize chemical reactions occurring in liquid environments, researchers have discovered a new reason lithium-oxygen batteries – which promise up to five times more energy than the lithium-ion batteries that power electric vehicles and cell phones – tend to slow down and die after just a few charge/discharge cycles.
