以含有模板剂(EO20PO70EO20, P123)的介孔SBA-15(P123-em-SBA15)为填料, 通过溶液浇铸法制得PEO-LiClO4-P123-em-SBA15全固态复合聚合物电解质. 实验表明, P123-em-SBA15可能通过其特有的拓扑结构而大幅度提高复合聚合物电解质的锂离子迁移数. 另外P123-em-SBA15还可以使体系的室温离子电导率提高两个数量级以上. 优良的锂迁移性能表明PEO-LiClO4-P123-em-SBA15复合聚合物电解质在全固态锂离子二次电池领域具有良好的应用前景.
PEO-LiClO4-P123-em-SBA15 solid-state composite polymer electrolytes were prepared by solution casting using mesoporous SBA-15 (P123-em-SBA15) -em-SBA15 may significantly increase the lithium ion mobility of the composite polymer electrolyte through its unique topological structure. In addition, the P123-em-SBA15 can also increase the ionic conductivity of the system by more than two orders of magnitude. Excellent lithium migration Performance PEO-LiClO4-P123-em-SBA15 composite polymer electrolyte in the field of all-solid-state lithium ion secondary batteries have good prospects.
