面向锂电储能系统的本质安全电池智能隔膜材料
摘要：为实现“碳达峰、碳中和”目标，构建安全稳定、绿色低碳的现代化能源体系，锂离子电池作为一种典型的电化学储能器件备受关注。如何在新增装机规模不断扩大的情况下，保证电站安全平稳运行成为了首要问题。为此，从电芯材料角度出发，针对目前商业锂电池隔膜存在的问题，综述了近年来智能隔膜方面的工作，包括聚烯烃隔膜材料改性、新型智能化隔膜结构设计和耐高温聚合物材料开发，强调了开发高安全性隔膜材料的重要性。最后，对液态和固态电池隔膜的研究方向进行了展望，以期为进一步设计高安全性的储能材料提供参考。
Abstract:In order to achieve the goal of “carbon peak, carbon neutrality” and build a safe, stable, green and low-carbon modern energy system, lithium-ion batteries have attracted much attention as a typical electrochemical energy storage device. How to ensure the safe and stable operation of the power stations has become the primary issue with the scale of newly installed capacity expanding. Therefore, from the perspective of cell materials, aiming at the existing problems of commercial lithium battery separators, the work of intelligent separators in recent years was reviewed, including the modification of polyolefin separator materials, the design of new intelligent separator structures and the development of high temperature resistant polymer materials. The importance of developing high-safety separator materials was emphasized. Finally, the future research on separators of liquid and solid batteries was prospected, in order to provide a reference for further optimization and design of high-safety energy storage materials.
