Abstract The unstable interface between reactive anodes and electrolytes in batteries has been identified as a critical factor limiting the long‐cycle stability of batteries. An effective solution is to build solid electrolyte interphase (SEI) that acts passivation layer mitigate side reactions electrolytes. mechanical SEI important because with poor cannot survive volume topography fluctuation anode upon cycling. stress built‐up would cause failure SEI, resulting exposure fresh surface electrolyte, consuming limited active materials electrolytes, inducing rapid battery decay. Therefore, understanding regulating imperative for improving cycle life. In this review, properties are discussed. Then, advanced characterization tools measure introduced. Additionally, recent progress on presented terms situ ex modifications SEI. Finally, an insightful outlook provided further understand regulate performance.

Published: Nov. 25, 2024

Nonaqueous lithium-based batteries have become a dominating stream of modern energy storage systems. Understanding the physicochemical processes and mechanisms electrode evolution interfacial reactions in lithium is highly desired to further improve their capabilities. Compared with ex situ testing techniques, situ/operando spectroscopic techniques are significant importance battery research because they can provide more dynamic transient information under working conditions. Herein, this review we systematically introduce various for development nonaqueous Li batteries, including infrared (IR) spectroscopy, Raman scattering (Raman) nuclear magnetic resonance (NMR) sum frequency generation vibrational spectroscopy (SFG-VS) X-ray absorption (XAS). The recent advances these especially applications studying materials electrode–electrolyte interphases, been comprehensively summarized. Finally, propose future potential research.
