EXAFS spectra acquired during the discharging process of the zinc half-electrode. (a) EXAFS signal as function of the photoelectron wavevector taken at different times during the zinc dissolution in the porous electrode; (b) corresponding Fourier transform of the EXAFS presented in (a) showing the main contribution of the Zn–O and Zn–Zn shells to the spectra. The arrow shows the direction of the process during the dissolution. |
