제목 Improved performance of single ion conducting polymer electrolyte based on polystyrene with an additive of lithium salt for lithium-ion batteries
초록 Recently, solid polymer electrolytes (SPEs) for lithium-ion batteries have drawn increasing attention due to their integrating advantages, including high safety, non-flammability and good flexibility, as well as interfacial compatibility, compared with liquid or gel-type electrolytes. In this work, we synthesized blending polymer electrolyte containing single li-ion, consisted of lithium poly [(p-styrenesulfonyl) (fluorosulfonyl) imide] (LiPSFSI) and poly (ethylene glycol) dimethacrylate (PEGDMA). Subsequently, the physico-chemical properties and cell performances of as-prepared electrolyte were carried out. Compared to LiPSFSI/PEGDMA blending electrolyte, the electrolyte of LiPSFSI/PEGDMA with a conducting lithium salt displays better thermal stability, excellent cycling stability and considerable transference number (tLi+). Besides, the LiPSFSI/PEGDMA electrolyte with an additive lithium salt, which exhibited higher ionic conductivity (σ) under the temperature range of 30-80 °C.
