Ionic liquids (ILs) have emerged as promising electrolytes not only because of their intrinsic safety but also due to their ability to stabilise electrogenerated species. Building on our previous studies of the oxygen reduction reaction (ORR) in neat triisobutyl(methyl)phosphonium ([P1i4i4i4]+)-based ILs and inspired by encouraging reports on sodium electrochemistry, we here investigate the electrochemical behaviour of [P1i4i4i4]+-based electrolytes combined with NaFSI and NaFTFSI (FSI = bis(fluorosulfonyl)imide anions) and FTFSI = fluorosulfonyl)(trifluoromethanesulfonyl)imide) salts. A comprehensive cyclic voltammetry study, complemented by impedance spectroscopy, Fourier transformed infrared, and 23Na nuclear magnetic resonance, identified the optimal electrolyte composition in terms of salt concentration and anion. Notably, the use of [P1i4i4i4][FSI] with 30 mol% NaFSI enabled a Na–O2 cell to sustain more than 100 cycles, representing the highest cycling stability reported to date for an IL-based electrolyte. These results underscore the critical role of electrolyte formulation on ORR/OER pathways and provide valuable electrochemical insights for the rational design of IL-based electrolytes for Na–O2 batteries.This study was supported by Ministerio de Ciencia, Innovación y Universidades (grant RYC2020-030104), Ministerio de Ciencia, Innovación y Universidades (PID2023-150574NB-I00), Gobierno de Aragón (grant T03_23R), and Centre of Excellence for Electromaterials Science, Australian Research Council (grant CE140100012).L.G.-Q., T.A.H., P.C.H., and C.P.-G. gratefully acknowledge financial support from the Australian Research Council (ARC) through the ARC Centre of Excellence for Electromaterials Science (ACES) (project ID: CE140100012).
