Fluoroether Design Enables High-Voltage All-Solid-State Lithium Metal Batteries.

ABSTRACT: Developing high-voltage all-solid-state lithium metal batteries (ASSLMBs) holds transformative potential for next-generation energy storage technologies but remains a formidable challenge. Herein, a new prototype design is presented that integrates fluorinated ether segments into the traditional oxide nanocomposite phase, enabling poly(ethylene oxide)-based composite electrolytes with exceptional anti-oxidation durability and enhance overall electrochemical performance. Through a combination of experimental and computational analyses, it is demonstrated that the superior performance is attributed to the formation of reconstructed Li⁺ solvation with weakly coordinating environments. The proposed formulation exhibits excellent Li-metal compatibility, enabling stable cycling in symmetric Li||
