Abstract Fluoride‐ion batteries (FIBs) represent a potential “next‐generation” electrochemical storage device, offering high energy density. However, the practical implementation of FIBs at room temperature is impeded by limitations currently available ceramic electrolytes. Here, composite NH 4 HF 2 @PEO@β‐PbSnF electrolyte with both conductivity 10 −4 S cm −1 and wide stability window (4.59 V vs Pb/PbF ) fabricated. Field emission transmission electron microscope (FETEM) demonstrates presence space charge region, which enhances conductivity. Furthermore, 19 F NMR density functional theory (DFT) calculations elucidate that interaction between Sn 2+ (Lewis acid) − base) induces significant modifications to electronic structure, critically contribute enhanced electrolyte. Integrating this promising high‐voltage CuF cathodes anodes, reversible coin cell discharge capacity 143 mAh g up 50 cycles demonstrated. The rational design such electrolytes offers pathway toward application temperature.

Due to the limitations of lithium‐ion batteries (LIBs), there is an urgent need explore alternative energy storage technologies. However, high‐energy density fluoride‐ion (FIBs) has attracted widespread attention as a potential successor LIBs. FIBs are emerging low‐cost, safe, and versatile solution, with broad operating temperature range. With continuous efforts from researchers, significant progress been made in field FIBs. Nevertheless, compared traditional batteries, research on remains limited, many challenges unexplored avenues persist. This article elucidates principles FIBs, summarizes materials for both cathodes anodes, discusses electrolytes, addresses existing issues. It also outlines future directions applications As it continued innovate explore, hold promise revolutionizing technology, offering enhanced performance, safety, sustainability.
