Low ionic conductivity and an unstable electrolyte/electrode interface are significant obstacles that impede the advancement of lithium-ion batteries (LiBs) in practical applications. This research endeavors to address these challenges by developing a cross-linked gel polymer electrolyte (C-GPE) utilizing epoxidized soybean oil (ESO) as its base material. The synthesis involves in situ thermal polymerization, employing lithium bis(fluorosulfonyl)imide (LiFSI) as the initiator. Furthermore, the incorporation of ethylene carbonate/diethylene carbonate (EC/DEC) proves advantageous in enhancing the distribution of the prepared C-GPE on the anode surface and facilitating the dissociation ability of LiFSI. The synthesized polymer undergoes analysis through techniques such as FT-IR, TGA, and DSC to evaluate its properties. Subsequently, the performance of the battery is assessed via a charge-discharge test to gauge its efficiency.
