Summary: The practical application of high-rate solid-state lithium metal batteries has been hindered by uncontrolled dendrite growth, poor rate performance, and insufficient mechanical strength of solid polymer electrolytes (SPE) due to crystallization-induced anisotropic ion transport. In this study, a robust ion-rectifying PEO-TOC membrane was developed by incorporating titanium-oxo clusters (TOC) into PEO-LiN(CF3SO2)2 (LiTFSI) electrolyte. The PEO-TOC membrane showed dendrite-free lithium metal deposition and achieved high-rate performance and good cycling performance, which is challenging for routine SPEs with anisotropic ion flux and mechanical properties.

Summary: All-solid-state Li-SeS2 batteries have advantages in thermal stability and energy density compared to traditional liquid Li-ion batteries. However, the low ionic conductivity of the solid-state electrolyte and poor kinetic property of the cathode composite limit their practical application. In this study, a high conductivity Li7P2.9W0.05S10.85 glass-ceramic electrolyte was designed using a traditional ball milling method, and an interpenetrating network strategy was proposed for rational cathode composite design. The assembled batteries showed improved capacity and rate capability, demonstrating the importance of an interpenetrating network for carrier transport in cathode composite.
