This study aims to improve the low thermal stability and flexibility of liquid electrolyte lithium ion batteries. As a substitute, gel polymers have attracted much attention as an electrolyte with excellent fire resistance, high efficiency and chemical stability. Thermal polymers broadly include monomers, oligomers, polymers or mixtures of the above-mentioned materials, where chemical reactions occur when heat is applied, resulting in profound changes in structures that substantially alter chemical and mechanical properties. Herein, we fabricated a single li-ion conducting blending polymer electrolyte, consisted of lithium poly [(p-styrenesulfonyl) (fluorosulfonyl) imide] (LiPSFSI) and poly (ethylene glycol) dimethacrylate (PEGDMA). Afterwards, the thermal properties and cell performances of as-prepared electrolyte were investigated.
