聚酰亚胺在锂离子电池高安全性隔膜的研究进展
Research progress on polyimide-based high-safety separators for lithium-ion batteries
总结了聚酰亚胺(polyimide,PI)隔膜的常见制备方法,重点综述了提升PI隔膜安全性的改性技术,深入分析了PI在热稳定性、阻燃性、高温热关断、机械性能及电解液亲和力方面的独特优势和作用机理,并对PI在未来电池隔膜中的应用进行总结与展望。
This review summarizes the preparation methods of PI separators,and focuses on modification strategies to improve the safety of PI separators.We analyze the unique merits and function mechanism of PI concerning thermal stability,flame retardancy,high-temperature thermal shutdown,mechanical porperties,and electrolyte affinity.Finally,we summarize and propose the outlook on the application of PI-based materials as LIBs separators.
