Order‐structured solid‐state electrolytes

Solid-state electrolytes (SSEs) are recognized as attractive candidates to realize safe and high-energy-density lithium metal batteries (LMBs). The anisotropic behavior induced by the orientation offers SSEs with desired properties targeting specific functions, and therefore the rational design of the order-structured SSE provides an alternative solution to achieve an ideal SSE. This review discusses the structure-property correlation of SSEs, and then summarizes the design strategies to construct order-structured SSEs. Finally, the current challenges and possible future research directions for order-structured SSEs for scalable high-energy-density LMBs are presented.
