报道了基于具有高浓度表面态的低粒径填料的纳米复合聚合物电解质的合成和性能。通过将Al2O3分散在P（EO）20LiCF3SO3 [PEO是聚环氧乙烷]基质中形成的这些电解质显示出更高的电导率，特别是比普通的无陶瓷的P（EO）20LiCF3SO3对应物高得多的锂迁移数。这些独特的性能使得纳米复合聚合物电解质作为新型锂可充电电池中的改进隔膜特别令人感兴趣。本文报道了以P（EO）20 LiCF3SO3 + 10wt%Al2O3为聚合物电解质，LiMn3O6为正极的电池性能。
The synthesis and the properties of nanocomposite polymer electrolytes based on low-particle size fillers having a high concentration of surface states are reported. These electrolytes that are formed by dispersing Al 2 O 3 in a P(EO) 20 LiCF 3 SO 3 [PEO is poly(ethylene oxide)] matrix, show higher conductivity and, particularly, much higher lithium transference number than those of common, ceramic-free P(EO) 20 LiCF 3 SO 3 counterparts. These unique properties make the nanocomposite polymer electrolytes of particular interest as improved separators in novel types of lithium rechargeable batteries. This paper reports the performance of a battery using a P(EO) 20 LiCF 3 SO 3 + 10 wt % Al 2 O 3 as the polymer electrolyte and LiMn 3 O 6 as the cathode.
