“…However, the choice of the carbon-based substrate depends on the specific requirements of the ZAB system, including design, performance targets, manufacturing, and cost considerations. It has been demonstrated that CP can be an efficient alternative to carbon cloth electrode substrates since it offers high surface area [41,42], modulable chemical surface, and electrochemical properties [43][44][45]. Moreover, the highly torturous porous structure and smooth surface of carbon papers were found to be an advantage under dry operating conditions [40], making them promise to alleviate electrolyte evaporation at the electrode side facing the air by optimizing wettability of PTFE-modified GDLs [19].…”

Rechargeable Zn–air batteries (ZABs) can play a significant role in the transition to a cleaner and more sustainable energy system due to their high theoretical energy density, high cell voltage, and environmental friendliness. ZAB’s air cathode is the principal determinant in predicting the battery’s overall performance, as it is responsible for catalyzing the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) during the discharging and charging process, respectively. In this work, a detailed optimization study of the architecture of the air cathode was carried out using the benchmark bifunctional oxygen electrocatalyst (Pt/C-RuO2). The air cathode composition and architecture were optimized regarding the choice of the commercial gas diffusion layer (GDL), the effect of hot pressing the catalyst layer (CL), and the optimum pore size of the current collector. The best cathode from this study shows a maximum power density (PDmax) of 167 mW/cm2, with a round trip efficiency and a voltage gap (Egap) of 59.8% and 0.78 V, respectively, indicating the air cathodes preparation approach proposed in this work as a promising strategy for the improvement of the overall performance of ZABs.
