利用溶剂转换法制备新型锂离子电池凝胶聚合物电解质(GPE).通过扫描电子显微镜(SEM)、傅里叶变换红外光谱(FTIR)、热重(TG)分析、广角X射线衍射(WXRD)、力学拉伸及交流阻抗等测试,分析了细菌纤维素凝胶聚合物电解质的微观形态、结构以及电化学性能,研究结果表明:室温下细菌纤维素凝胶聚合物电解质的离子电导率高达1.6×10-2S/cm,拉伸强度达到39.8MPa,其在锂离子电池开发中具有良好的应用前景.%Novel gel polymer electrolytes (GPE) were prepared by means of solvent conversion process. The microscopic morphology, structure and electrochemical properties of the GPE were characterized by a variety of techniques such as scanning electronic microscope (SEM), Fourier transform infrared spectroscopy(FTIR), thermogravimetry (TG) analysis, wide-angle X-ray diffraction(WXRD), tensile test and alternating current(AC) impendance. The research results indicated that the ionic conductivity of the bacterial cellulose gel polymer electrolyte was 1.6×10-2S/cm at room temperature, and the stress was about 39.8 MPa, which makes it has a good application prospect in lithium-ion batteries.
