a CV curve of the Cu2O electrode after 50 charge/discharge cycles at a scan rate of 0.5 mV s−1 in 0.6 M NaCl solution at pH = 7., with identified stages. No iR compensation. b Charge contribution of each peak in the CV curve; c Potential profile of Cu2O electrode with identified stages. d Illustration of homemade in-situ PXRD cell. This cell is a three-electrode system with reference electrode (RE), counter electrode (CE) and working electrode (WE). e Charge/discharge profile obtained during in-situ PXRD measurement; f Corresponding in-situ PXRD pattern collected during a single charge/discharge cycle; g Schematic illustration of crystal structure evolution during the reversible electrochemical reaction.
