双氟磺酰亚胺盐的合成研究进展
Research progress on synthesis technology of bis(fluorosulfonyl)imide salts
摘要
Abstract
Bis(fluorosulfonyl)imide salts(MFSI)are important fluorine-containing compounds.Lithium-ion batteries and sodium-ion batteries with electrolytes containing MFSI as the main salts have demonstrated excellent overall electrochemical performance.With the rapid development of the new energy industry,the synthesis of MFSI has received widespread attention and research.This paper primarily focused on the application of MFSI in the battery field,thoroughly discussed its synthesis process and purification methods,and then briefly introduced the preparation equipment and large-scale production status of lithium bis(fluorosulfonyl)imide(LiFSI).Based on the above analysis,the paper further analyzed the existing problems in MFSI synthesis technology,and proposed that the exploration of the mechanism of the fluorination process of MFSI and the development of a safe and efficient catalytic fluorination process were the main directions for the future research.This article aimed to provide reference for the optimization and upgrade of MFSI synthesis technology,and further promoting the industrialization process of high-performance lithium-ion and sodium-ion batteries.关键词
