a Ex situ synchrotron HRXRD characterization of TNO. b Ex situ synchrotron HRXRD characterization of TNO−x@C3. c In situ synchrotron HEXRD characterization voltage profile and corresponding contour plot of the XRD pattern evolution of TNO during the first charge–discharge process. d In situ synchrotron HEXRD characterization voltage profile and corresponding contour plot of the XRD pattern evolution of TNO−x@C3 during the first charge–discharge process. (Contour plot of the (011), (400), (317), and (700) peaks evolution).
