In this study, we developed a specially designed fluorocarbon–PEO graft copolymer–based solid polymer electrolyte that delivers:

🔹 ~10× higher ionic conductivity than pristine PEO at room temperature. 

🔹 A high Na⁺ transference number (~0.46), among the highest reported for PEO-based systems. 

🔹 Superior thermal stability, making it a strong candidate for safer, high-performance all-solid-state sodium-ion batteries.
