Elucidation of the Solid Electrolyte Interphase Formation Mechanism in Micro‐Mesoporous Hard‐Carbon Anodes (Adv. Mater. Interfaces 8/2022)

Micro-Mesoporous Hard Carbons as Sodium-Ion Battery Anodes In article number 2101267, Hande Alptekin, Maria Crespo-Ribadeneyra, Maria-Magdalena Titirici, and co-workers investigate hard carbons with tailored bimodal porosities as sodium-ion anodes. The nature of the innermost solid electrolyte interphase (SEI) sub-layer controls the performance. F-containing salts enable a stable SEI, yet enhanced electrolyte decomposition seems unavoidable in carbonate-based solvents compared to ether-based systems.
