Fig. 1: Dynamics of PPGA in ZnSO4 electrolyte.
From: A parts-per-million scale electrolyte additive for durable aqueous zinc batteries
a The interaction between PPGA and H2O. b FTIR spectra of BZS with a varying amount of PPGA (0, 1, 5, or 10 ppm), where BZS was used to subtract the background. c 1H NMR spectra of BZS electrolyte and that with 5 ppm PPGA. d MD simulation of PPGA (marked by a green ellipsoid) and e corresponding energy evolution. f XRD patterns of zinc metal treated with studied electrolytes. The inset in (a) denotes the electrostatic potential map of PPGA. In (a and d), the color scheme for the spheres is as follows: red is oxygen, white is hydrogen, gray is carbon, light gray in (d) is zinc, pink is phosphor, and yellow represents sulfur atoms.
