Super SEI‐Forming Anion for Enhanced Interfacial Stability in Solid‐State Lithium Metal Batteries

Advanced Materials, Год журнала: 2024, Номер 36(47)

Опубликована: Окт. 9, 2024

Abstract The extremely high chemical reactivity of lithium metal (Li°) electrodes and its enormous volume change during repetitive cycles cause continuous interfacial degradations in prevailing organic electrolytes, thus deteriorating the cycling performances rechargeable batteries (LMBs). Herein, departing from traditional wisdom on design electrolyte components, a super SEI‐forming anion (SSA), as an efficient percussor for building stable interphases Li° electrode, is proposed. Comprehensive investigations related to unique chemistry SSA reveal that sulfonate polyfluoroalkyl functionalities synergistically contribute uniform spatial distributions designer species, greatly improving surface coverage property conformal ability resulting interphases. Consequently, incorporation leads significant improvements cyclability electrode (exceeding 575 mAh cm −2 before failure) corresponding Li°||LiFePO 4 cells [a five‐time increase lifespan compared benchmark cell with popular bis(fluorosulfonyl)imide (FSI)]. present work offers paradigm shift tame notorious issues via upgraded chemistry, which can promote practical development LMBs other kinds batteries.
