摘　　要：介绍了以聚偏氟乙烯-六氟丙烯共聚物[P(VDF-HFP)]为基质的凝胶聚合物电解质(GPE)的制备方法和性质,如萃取法、相转化法及直接法等;讨论了该类电解质的主要问题,例如热力学稳定性和机械强度较差等,并提出了可能的解决措施,如共混、加入陶瓷粒子等。The preparation methods and performance of gel polymer electrolyte （GPE） based on poly （vinylidene fluoridehexafluoropropylene） [P（VDF-HFP）] were introduced, such as extraction method, phase inversion method and direct method. The main problems of this kind of electrolyte, including lower thermodynamic stability and mechanical strength, were discussed. The possible solutions such as blends and incorporation of ceramic fillers were put forward.
