| 内容記述 | The 3d transition metal oxides with layered structures, NaxMO2 (M = Mn, Co), are promising cathode materials for Na-ion secondary batteries. Here, we investigate the electronic structure of the M of four layered oxides (Na0.91CoO2, Na0.66CoO2, Na1.00MnO2, and Na0.54MnO2) by means of high energy resolution fluorescence detected X-ray absorption near-edge structure, which utilizes the 1s core-hole lifetime-broadening reduction. The highly energy-resolved spectroscopy reveals a shoulder structure in the pre-edge regions of the Co K-edge spectra in Na0.91CoO2. The structure is ascribed to the transition to the Co 3d/4p states via slight hybridization with the Na 3s state. | |||||
