ABSTRACT Sodium batteries are a suitable alternative to lithium due the limited availability of metal resources. Research on polymer electrolytes based poly(methyl methacrylate) (PMMA) in sodium has been limited. However, studies PMMA‐based have shown that use fillers is an effective method for improving ionic conductivity PMMA. Another approach can significantly enhance this type electrolyte introduction porosity into electrolyte. In present study, electrochemical properties porous PMMA investigated. The cross‐linked gel (GPEs) prepared via photopolymerization technique, and achieved through etching using solvent. results showed enhances GPEs sodium‐ion batteries. optimized GPE exhibited 1.56 mS cm⁻¹ at room temperature, excellent stability (upper 4.5 V), specific capacity 138.9 mAh g −1 . These findings highlight potential development high‐performance ion batteries, offering viable pathway toward next‐generation energy storage technologies.
