(a) Schematic illustration of the operando XAFS measurements. (b) Photograph of the experimental setup on a synchrotron XAFS beamline. (c) Electrochemical profile of the potentiostatic measurements with stepwise increased potentials from 1.2 to 1.6 V versus RHE, with each potential step held for 10 min, during which XAFS data are continuously collected. (d) Operando XANES spectra of LiCoO2 at different potentials in 0.1 M KOH. (e) Shifts of the white line of the Co K-edge spectra. (f) Schematic illustration of the reaction mechanism depicting the dynamic cation intercalation and deintercalation, and the structural evolution of LiCoO2, during OER.
