Scientists Probe Lithium-Sulfur Batteries In Real Time Video

Johanna Nelson uses powerful X-ray imaging to study lithium-sulfur batteries, a promising technology that could some day power electric vehicles. Working with scientists at SLAC and Stanford University, Nelson took microscope snapshots of individual sulfur particles -- the first real-time imaging of a lithium-sulfur battery in operation. Previous studies using standard electron microscopes showed that large amounts of sulfur disappears from the cathode after cycling, causing the battery to die. But Nelson's...
