Geometric Design of Interface Structures and Electrolyte Solvation Chemistry for Fast Charging Lithium‐Ion Batteries (Adv. Mater. 19/2025)

Geometric Design Strategy for Solid Electrolyte Interphase In article number 2418773, Jong-Won Lee, Seungbum Hong, Nam-Soon Choi, and colleagues demonstrate that a solid electrolyte interphase enriched with small grains enhances Li+ ion transport by providing abundant pathways. Moreover, a soft-solvating environment improves the desolvation kinetics of solvated Li+ ions under fast-charging conditions. Additionally, replacing ethylene carbonate with isobutyronitrile enables a high discharge capacity during rapid charging while mitigating Li plating.
