Fig. 6From: Lithia-Based Nanocomposites Activated by Li2RuO3 for New Cathode Materials Rooted in the Oxygen Redox ReactionXPS spectra of the lithia/Li2RuO3 nanocomposites measured at various charging and discharging points. For the measurement, the nanocomposites were charged to 350 and 500 mAh g−1 (assigned as full charge), and discharged to 250 and 500 mAh g−1 after full charge. a O 1 s spectra, b Ru 3d spectra, and c Ru 3d5/2 spectraBack to article page
