a RDFs for Zn2+−O pairs in HE. b FT-IR absorption and second derivative spectra for AE and HE. c 1H NMR spectra for pure water, AE and HE. d Deprotonation (H+ dissociation of H2O) energy from Zn2+ inner solvation shell of AE and HE. e ESW for AE and HE measured with 10 µm Pt ultramicroelectrode as working electrode at a scan rate of 1 mV s−1. f CE for Zn||Cu cells using AE and HE as the electrolyte, respectively. The current density is 1 mA cm−2 and the plating capacity is 1 mAh cm−2.
