Abstract
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.
