Self-Adaptive Superionic Electrolytes via Multiple-Cation Modulation for All-Solid-State Lithium–Metal Batteries

) and low temperature (-30 °C). Besides, such solid-state electrolytes can be extended to other all-solid-state lithium-metal rechargeable batteries. This scalable dual-cation modulation strategy provides a general and practical route to construct superionic electrolytes with compatibility with an anode by in situ interfacial and lithium metal decoration, advancing the realistic application of next-generation all-solid-state lithium-metal batteries.
