摘　　要：锂离子电池由于形状多样化、灵活性及轻便等优点而用于商业化生产,满足微型电子工业的需要,而偏氟乙烯和六氟丙烯的共聚物PVDF-HFP由于较高的电导率,较好的机械强度和热稳定性,优良的界面特性和电化学性能而被认为是最受欢迎的一种聚合物电解质。主要综述了PVDF-HFP固体电解质的组成、制备方法和进展,讨论了PVDF-HFP电解质的改性措施:填料改性、增塑剂改性、共聚共混改性及聚合物改性。对今后的发展方向作了简单展望。The lithium ion batteries are commercialized due to their shape versatility, flexibility, and lightness and can meet the demands of microelectronic industries. Poly （vinylidenefluoride-co-hexafluoropropylene） （PVDF-HFP） is one of the most popular polymers for gel polymer electrolytes （GPE） because of its high ionic conductivity, good mechanical, thermal, interfacial, and electrochemical stabilities. In this paper, the progress and the composition of solid polymer electrolyte based on PVDF-HFP was reviewed briefly and the preparation technology of the polymer electrolyte was introduced. The influences on the properties of the polymer electrolyte were analyzed. The progress of modified the polymer electrolyte were discussed, including the modification of filler, plasticizer, polymer, copolymerization and blending technologies. The development of polymer electrolyte in the future was also suggested.
