Nature Energy, Published online: 06 March 2026; doi:10.1038/s41560-026-01994-y Electrolyte solvents in sodium-ion batteries have long been regarded as passive ion-transport media, while sluggish Na+ diffusion in layered cathodes limits kinetics. Now, researchers show that reversible solvent intercalation actively enhances Na+ transport, enabling fast kinetics with preserved redox chemistry and cycling stability.
