Fig. 5 Fine structure characterization and theoretical analysis of the dual-ion storage mechanisms. (a) Mn K-edge XANES spectra of Rec-Mg-MnO2 at different charged states. (b) The k3-weight Fourier transform of the Mn K-edge EXAFS spectra. (c) Wavelet transform of the k3-weighted Mn K-edge EXAFS signals of Rec-Mg-MnO2 at different charged states. (d) Charge density difference of MnO2@PEI (green and orange represent the charge depletion and accumulation). (e) The removal energy of active MnOx fragments in the MnO2@PEI and pure d-MnO2 structure. (f) The corresponding adsorption energy for H+ and Mg2+ at different sites. (g) Mg2+ (above) and H+ (below) migration pathways along path-A/B and the corresponding diffusion barrier.
