a Polarization curves for S-Cu-ISA/SNC and the references. b The contrast between S-Cu-ISA/SNC and the references for Jk (0.85 V) and E1/2. c Contrasting the Eonset and E1/2 values for S-Cu-ISA/SNC and the catalysts in Supplementary Table 2. d The polarization curves of S-Cu-ISA/SNC at different rotating speeds. e The K-L plots for S-Cu-ISA/SNC. f The long-term durability tests of S-Cu-ISA/SNC, which was assessed by cycling the catalyst between 1.1 and 0.2 V vs. RHE at 50 mV s−1. g Schematic diagram of Zn-air battery. h Discharge polarization curves and power density plots of S-Cu-ISA/SNC and Pt/C-based Zn-air batteries.
