We discuss how x-ray Compton scattering spectra can be used for investigatingthe evolution of electronic states in cathode materials of Li batteries underthe lithiation/delithiation process. In particular, our analysis of the Comptonspectra taken from polycrystalline LixCoO2 samples shows that the spectra aredominated by the contribution of the O-2p redox orbital. We identify a distinctsignature of d-orbital delocalization, which is tied directly to theconductivity of the material, providing a descriptor based on Compton spectrafor monitoring the lithiation range with improved conductivity and kinetics forelectrochemical operation. Our study demonstrates that Compton scatteringspectroscopy can provide a window for probing complex electronic mechanismsunderlying the charging and discharging processes in Li-battery materials.
