Fig. 1: Characterization and simulation of electrolytes.
a Schematic illustration of the effects of the PS molecule on electrolyte and interfacial chemistry for 1 M Zn(OTf)2 electrolyte and electrolyte with 1 wt% PS. b 67Zn NMR, c 17O NMR in OTf−, d FTIR spectra, and e Raman spectra of the 1 M Zn(OTf)2 electrolytes with different concentrations of PS. f 3D snapshots of electrolyte with 1 wt% PS obtained from MD simulations, and the dashed profile is a partially enlarged snapshot for the solvation structure of Zn2+. g The radial distribution functions and coordination number of Zn2+-O collected from MD simulations. h Zn K-edge XANES spectra, and the intensity is normalized to the edge jump for quantitative comparison. i Fourier transform EXAFS curves and j Wavelet transforms of Zn K-edge XANES of 1 M Zn(OTf)2 electrolyte and electrolyte with 1 wt% PS. k The Zeta potential of 1 M Zn(OTf)2 electrolyte and electrolyte with 1 wt% PS. l Contact angles of 1 M Zn(OTf)2 on bare Zn foil (I) and the Zn foil pre-soaked in 1 M Zn(OTf)2 for 7 days (III), and contact angles of electrolyte with 1 wt% PS on bare Zn foil (II), and the Zn foil pre-soaked in electrolyte with 1 wt% PS for 7 days (IV).
