a Operando XRD patterns and b Operando Ni K edge XANES spectra of LiNiO2 under applied potentials of 1.41–1.81 V in 1 M KOH solution. Diffraction peaks in low 2θ ranges and the pre-edge peak were magnified in the corresponding insets. A set of extra peaks are from graphitic carbon and broad diffraction peaks at 12° and 18° from the sample holder.
