【摘要】为了提高基于聚氧化乙烯（PEO）的聚合物电解质的室温电导率,以PEO为聚合物主体、LiClO4或LiN（CF3SO2）2为盐、SiO2为填充剂,以溶液浇铸法制备了它的复合聚合物电解质。电导率测试表明,PEO15LiN（CF3SO2）2-10％SiO2在30℃的电导率为4.67×10-5S/cm。更多还原

【Abstract】 To improve the ambient conductivity of polyethylene oxide (PEO)-based polymer electrolyte, the composite polymer electrolyte was prepared by the solution-casting with PEO as polymer matrix, LiClO4 and LiN(CF3SO2)2 as salt and SiO2 as filler. Conductivity measurement showed the conductivity of PEO15LiN(CF3SO2)2-10%SiO2 at 30癈 was 4.67 x 10-5S/cm.更多还原
