电纺EVOH磺酸锂/TiO2聚合物电解质电性能的研究

摘要

将纳米二氧化钛加入到EVOH-SO3Li中制备纺丝液，利用高压静电纺丝法制备EVOH-SO3Li/TiO2复合膜。组装扣式电池，测试EVOH-SO3Li/TiO2聚合物电解质的电化学稳定窗口及离子电导率。结果表明：复合薄膜的电化学性能稳定，离子电导率达到0.96×10-3s/cm。%The TiO2 was added into EVOH-SO3Li spinning solution, and then the EVOH-SO3Li/TiO2 composite membrane was prepared by elec-trospinning. The button cell was assembled to test the electrochemical stability window and ionic conductivity of EVOH-SO3Li polymer electrolyte. The results showed that the electrochemical performance of composite membrane was stable, and the ionic conductivity reached 0.96 ×10-3s/cm.
