Abstract:<\/h4>\n
Solid polymer electrolytes (SPEs) are gaining attention as viable alternatives to traditional aqueous electrolytes in zinc-air batteries (ZABs), owing to their enhanced performance and stability. In this study, anion-exchange solid polymer electrolytes (A-SPEs) were synthesized via electrophilic aromatic substitution and substitution reactions. Thin films were prepared using the solvent casting method and characterized using proton nuclear magnetic resonance (\u00b9H-NMR), Fourier-transform infrared spectroscopy (FT-IR), and thermogravimetric analysis (TGA). The ion-exchange capacity (IEC), KOH uptake, ionic conductivity, and battery performance were also obtained by varying the degree of functionalization of the A-SPEs (30 and 120%, denoted as PSf30\/PSf120, respectively). The IEC analysis revealed that PSf120 exhibited a higher quantity of functional groups, enhancing its hydroxide conductivity, which reached a value of 22.19 mS cm-1<\/sup>. In addition, PSf120 demonstrated a higher power density (70 vs. 50 mW cm-2<\/sup>) and rechargeability than benchmarked Fumapem FAA-3-50 A-SPE. Postmortem analysis further confirmed the lower formation of ZnO for PSf120, indicating the improved stability and reduced passivation of the zinc electrode. Therefore, this type of A-SPE could improve the performance and rechargeability of all-solid-state ZABs.<\/p>\n","protected":false},"excerpt":{"rendered":"DOI: 10.3390\/membranes15040102 Authors: Luis Javier Salazar-Gast\u00e9lum, Alejandro Arredondo\u2010Esp\u00ednola, Sergio P\u00e9rez\u2010Sicairos, Lorena \u00c1lvarez\u2010Contreras, No\u00e9 Arjona, Minerva Guerra\u2010Balc\u00e1zar Abstract: Solid polymer electrolytes (SPEs) are gaining attention as viable alternatives to traditional aqueous electrolytes in zinc-air batteries (ZABs), owing to their enhanced performance and stability.
