Nature Communications, Published online: 05 May 2026; doi:10.1038/s41467-026-72471-z Iron fluoride electrodes show contrasting stability in ether- and ester-based electrolytes. Here, the authors reveal that interfacial anion chemistry governs conversion pathways and phase evolution, explaining the origin of stability differences and guiding the design of high-energy lithium batteries.
