a An Open-circuit voltage. Inset: Schematic illustration of a ZAB. b Polarization curve and the recorded power density for the Co-N-Mn/NC or commercial Pt/C catalyst-based ZAB, respectively. c Rate performance of the ZABs with Co-N-Mn/NC or commercial Pt/C as air-cathode at different current densities. d Galvanostatic discharge curves of Co-N-Mn/NC or commercial Pt/C-based ZAB at j = 10 mA cm−2. e Long-term discharge-charge curves at j = 5 mA cm−2 for ZABs with Co-N-Mn/NC+ IrO2 and commercial Pt/C + IrO2. Inset: the corresponding voltage efficiency curves during the cycling test. Source data are provided as a Source Data file.
