Structural changes of chemically lithiated γ-MnO2 during chemical oxidation were characterized by X-ray diffraction combined with a stacking fault analysis and neutron total scattering with a local structure analysis. Lithium ions intercalate into the crystallographic sites around “Ruetschi” protons prior to those around “Coleman” protons for the chemically lithiated γ-MnO2. The “Ruetschi” and “Coleman” protons have O–H bond lengths of 1.2 A and 1.9 A, respectively, which decreased after the… CONTINUE READING
