Manganese-rich layered oxide cathodes of sodium-ion batteries (SIBs) are extremely promising for large-scale energy storage owing to their high capacities and cost effectiveness, while the Jahn-Teller (J-T) distortion low operating potential Mn redox largely hinder practical applications. Herein, we reveal that annealing in argon rather than conventional air is a universal strategy comprehensively upgrade Na-storage performance Mn-based cathodes. Bulk oxygen vacancies introduced via this method, leading reduced valence, lowered 3d-orbital level, formation new-concept domains. As result, density model P2-Na0.75 Mg0.25 Mn0.75 O2 cathode increases by ≈50 % benefiting from improved specific capacity redox. The domains can disrupt cooperative J-T distortion, greatly promoting cycling stability. This exciting finding opens new avenue towards high-performance SIBs.

Although studies of transition metal sulfides (TMS) as anode materials for sodium-ion batteries are extensively reported, the short cycle life is still a thorny problem that impedes their practical application. In this work, new capacity fading mechanism TMS electrodes demonstrated; is, parasitic reaction between electrolyte anions (i.e., ClO4- ) and yields non-conductive unstable solid-electrolyte interphase (SEI) meanwhile, corrosively turns into less-active oxides. This knowledge guides development an electrochemical strategy to manipulate anion decomposition construct stable interface prevents extensive reactions. It shown introducing sodium nitrate radically changes Na+ solvation structure by populating ions in first sheath, generating conductive SEI layer containing both Na3 N NaF. The optimized enables iron sulfide stably over 2000 cycles with negligible loss, similar enhancement performance demonstrated on number other sulfides. work discloses sulfides' cycling failure from unique perspective highlights critical importance manipulating chemistry batteries.
