Electron Microscope Images

Caption

Electron microscope images zoom in to show details of the NMC cathode particles. From left: Hollow NMC spheres, just 10 millionths of a meter in diameter, are made up of much smaller particles about 100 billionths of a meter across, visible in the second image. The third image is a close-up of a few of these nanoscale particles. At right, the microscope zooms in on the interface between two nanoscale particles, revealing individual atoms. The particles are slightly offset in a way that allows lithium ions from the battery's electrolyte to move in and out (arrow) during charging and discharging.
