| Abstract Scope |
Lithium-sulfur (Li-S) batteries hold great promise for next-generation energy storage systems owing to their high theoretical energy density and cost-effectiveness. However, the practical application of Li-S batteries is hindered by the severe shuttle effect of lithium polysulfides and the unstable lithium metal anode. In this work, we employed a physical vapor deposition (PVD) technique to grow a uniform layer of garnet-type solid-state electrolyte Li7La3Zr2O12 (LLZO) on the surface of a polypropylene (PP) separator. The LLZO coating effectively suppresses the migration of lithium polysulfides through the separator, thereby mitigating the shuttle effect. Moreover, the chemically stable and mechanically robust LLZO layer enhances interfacial stability at the lithium metal anode, reducing dendritic growth and improving cycling performance. This strategy provides a feasible approach to simultaneously address polysulfide shuttling and anode degradation in Li-S batteries. |
