The employment of lithium metal anode in rechargeable lithium batteries has been hindered by the safety concerns which are associated with the uncontrolled lithium dendrite growth and the unceasing side reactions with liquid electrolytes. In this work, we report that the use of Ti-containing solid electrolyte-coated separators can greatly enhance the cycle performances of lithium metal anode in cells using liquid electrolytes. The detailed morphologic studies indicate that more uniform lithium deposition is achieved in cells using Ti-containing solid electrolyte-coated separators than that using Al2O3-coated separators, which is likely due to the modified anode and electrolyte interfacial properties induced by the reactive nature of Ti-containing solid electrolytes with metallic lithium. This work demonstrates an effective strategy to enhance the homogeneity of lithium deposition, which leads to the stable cycling of lithium metal anode in rechargeable lithium-ion batteries. Texture intensity decreases by the increase in the amount of alloying elements

通过使用涂有含钛固体电解质的聚合物隔膜提高锂金属负极的循环稳定性

锂金属负极在可充电锂电池中的应用受到与不受控制的锂枝晶生长和与液体电解质不断副反应相关的安全问题的阻碍。在这项工作中，我们报告说，使用含钛的固体电解质涂层隔膜可以大大提高使用液体电解质的电池中锂金属负极的循环性能。详细的形态研究表明，与使用 Al2O3 涂层隔膜相比，使用含 Ti 固体电解质涂层隔膜的电池可实现更均匀的锂沉积，这可能是由于 Ti 的反应性质引起的负极和电解质界面性质的改变-含金属锂的固体电解质。这项工作展示了一种提高锂沉积均匀性的有效策略，从而导致可充电锂离子电池中锂金属负极的稳定循环。织构强度随着合金元素量的增加而降低
