摘　　要：随着锂离子电池的发展,其能量密度也已经接近极限。为了克服锂离子电池的理论容量限制,对于具有高能量密度的锂金属电池的研究被重新提起。然而,由于锂的高反应活性,使用过量的锂会增加安全风险,并降低锂金属电池的能量密度。这种矛盾促使了无负极锂金属电池构型的提出。无负极锂金属电池由于其高能量密度、更安全的制造流程,已成为一个有希望解决锂金属电池安全问题的候选者。然而,负极界面上有限的活性材料和界面反应导致其循环寿命差,阻碍了其实际应用。因此,寻找合适的策略提高无负极锂金属电池的循环稳定性对于促进高能量密度储能系统的实际应用具有重要意义。With the development of lithium ion batteries, the energy density of lithium ion batteries has also approached the limit. In order to overcome the theoretical capacity limitations of lithium ion batteries, the research on lithium metal batteries with high energy density has been revived. However, due to the high reactivity of lithium, using excessive lithium can increase safety risks and reduce the energy density of lithium metal batteries. This contradiction led to the proposal of the configuration of anode free lithium metal batteries. Due to its higher energy density and safer manufacturing process, the anode free lithium metal battery has become a promising candidate to solve the safety problem of lithium metal battery. However, the limited active materials and interfacial reactions on the anode interface lead to poor cycle life, which hinders its practical application. Therefore, it is of great significance to find suitable strategies to improve the cycle stability of the anode free lithium metal battery for promoting the practical application of the high energy density energy storsge system.
