摘　　要：锂金属电池作为下一代高能量密度电池的代表,近年来受到了广泛的关注和研究。然而,锂金属电池的商业化应用依然面临着重大的挑战,如锂枝晶的不可控生长和电解质界面稳定性差导致电池的循环性能较差,甚至引发严重的安全问题。蒙脱土因其独特的结构,大的比表面积以及良好的热稳定性,有望用于锂金属电池中来提高其电化学性能。因此,在锂金属电池中引入蒙脱土基材料被认为是解决上述问题最有效的方法之一。综述了用于高性能锂金属电池的蒙脱土基材料、改性策略等相关研究进展,并对其未来发展进行了展望。Lithium metal batteries,as the representative of the next generation of high-energy density batteries,have received widespread attention and research in recent years.However,the commercial application of lithium metal batteries still faces significant challenges,such as the uncontrolled growth of lithium dendrites and poor electrolyte interface stability,leading to poor cycling performance and even serious safety issues.Due to its unique structure,large specific surface area and good thermal stability,montmorillonite is expected to be used in lithium metal batteries to improve their electrochemical performance.Therefore,introducing montmorillonite-based materials into lithium metal batteries is considered as one of the most effective methods to solve the aforementioned problems.This review summarized the research progress on montmorillonite-based materials and corresponding modification strategies for high-performance lithium metal batteries,and their future prospects are also proposed.
