Sulfate-Pyrophosphate Cathodes with Dual-Anion Synergy for High-Performance Sodium Storage.
Cathode materials for sodium-ion batteries (SIBs) require a balance between capacity, rate capability, and cycle life. This study employs an anhydrous precursor approach to investigate the novel polyanionic cathode, Na2Fe2P2O7SO4 (NFPS). By regulating the carbon coating content derived from biomass, we achieve synergis...
