Platelet-Shaped Lithium Cobalt Phosphate Crystals (IMAGE) Technical University of Munich (TUM) Caption Electron microscope image of the platelet-shaped lithium cobalt phosphate crystals. Since the crystals are only a few hundred nanometers thick and the axis of maximum ionic conductivity is oriented towards the surface, the lithium ions need to move only short distances within the crystal.
