Interfacial‐Catalysis‐Enabled Layered and Inorganic‐Rich SEI on Hard Carbon Anodes in Ester Electrolytes for Sodium‐Ion Batteries (Adv. Mater. 29/2023)

Sodium-Ion Batteries In article number 2300002, Yu Li, Chuan Wu, Ying Bai, and co-workers develop an efficient strategy to reconstruct the surface functionality of hard carbons in situ, which can controllably catalyze preferential salt decomposition to form an inorganic-rich and layered solid electrolyte interphase (SEI). The structurally stable and ion-conductive SEI enables advanced hard carbon anodes with an ultrahigh initial Coulombic efficiency and long cycling life for sodium-ion batteries.
