Abstract
- Lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) is a widely used lithium (Li) salt that is extensively studied in the field of electrolytes for Li‐ion batteries (LIBs) to improve their performance. A thorough understanding of its underlying mechanisms in LIBs is crucial for gaining deeper insights into its future development. This paper provides an extensive review of the role of LiTFSI in enhancing battery performance, including its benefits for negative electrode protection, the facilitation of fast charging capabilities, and the promotion of battery operation across a wide temperature range. It also highlights the specific drawbacks of LiTFSI in the electrolyte domain and examines potential solutions. By leveraging the unique properties of LiTFSI, the strategies for its effective utilization in current research are outlined. Finally, the paper discusses the lack of research into the mechanism of LiTFSI in interface protection, particularly the evolution mechanisms of multi‐component Li salts at the positive and negative electrode interfaces, and it reasonably anticipates the potential applications of LiTFSI in the realm of non‐liquid batteries. This study not only provides a more comprehensive and profound understanding of LiTFSI but also aids in the exploration of novel electrolyte systems. [ABSTRACT FROM AUTHOR]
