抄録

Electron energy loss spectroscopy combined with a transmission electron microscope was applied to valence analysis of transition metal ions in LiMn2O4, LiMnTiO4, LiMnCrO4 and LiMnCoO4 powder samples. The transition metal 2p multiplet structures were compared with those of appropriate reference samples. The Mn, Ti and Co valences were clearly determined from the 2p spectra as LiMn3+Mn4+O4, LiMn3+Ti4+O4 and LiMn4+Co3+O4, respectively. The O 1s spectra were also effective for analysis of Cr in LiMnCrO4 and showed that the Cr ion was trivalent. The electron configuration of one of nominally tetravalent chromium compounds, CrO2, is also discussed.
