Lithium metal batteries are considered "rough diamonds" in electrochemical energy storage systems. Li-metal anodes have the versatile advantages of high theoretical capacity, low density, and low reaction potential, making them feasible candidates for next-generation battery applications. However, unsolved problems, such as dendritic growths, high reactivity of Li-metal, low Coulombic efficiency, and safety hazards, still exist and hamper the improvement of cell performance and reliability. The use of functional separators is one of the technologies that can contribute to solving these problems. Recently, functional separators have been actively studied and developed. In this paper, we summarize trends in the research on separators and predict future prospects.
锂金属电池在电化学储能系统中被视为“璞玉”。锂金属负极具有理论容量高、密度低和反应电位低等多种优势,使其成为下一代电池应用的可行候选者。然而,诸如枝晶生长、锂金属的高反应活性、低库仑效率和安全隐患等未解决的问题仍然存在,并阻碍了电池性能和可靠性的提升。使用功能隔膜是有助于解决这些问题的技术之一。近年来,功能隔膜得到了积极的研究和开发。在本文中,我们总结了隔膜的研究趋势并预测了未来前景。
