Battery Composition (IMAGE) DOE/Lawrence Berkeley National Laboratory Caption Atomic resolution scanning transmission electron microscopy images and electron diffraction patterns, arranged on a rendering of a battery, show how the structure of lithium-rich and manganese-rich transition metal oxides used inside battery cathodes changes with composition. The images also show how the surface of the cathode has a different structure than the interior.
