Figure 5. ZAB performance of Fe-N-C NA and the commercial Pt/C benchmark. (A) scheme of the prototype ZAB with Fe-N-C NA or Pt/C as cathodes; (B) discharge polarization and power density curves; (C) galvanostatic discharge curves at various current densities; (D) the discharge curves at a constant current density of 10 mA·cm-2. ZAB: Zinc-air battery; NA: nano-assembly.
