Figure 5. (A) OCV plots of SWZABs assembled with Co-N₄Cl-C, Co-N₄-C, and Pt/C catalysts using simulated alkaline seawater electrolyte (6 M KOH and 0.5 M NaCl); (B) Discharge polarization curves and power density plots of Co-N₄Cl-C-, Co-N₄-C-, and Pt/C-based SWZABs; (C) Specific capacity by mass normalization at a constant current density of 10 mA·cm^-2; (D) Galvanostatic discharge curves at various current densities ranging from 3 to 20 cm^-2. OCV: Open-circuit voltage; SWZABs: seawater-based zinc-air batteries.
