摘　　要：制备了PVDF-HFP/AgClO4-丙酮高分子固体电解质,用差示扫描量热法(DSC)、X射线衍射光谱法(XRD)及阻抗测量表征了电解质的性能。该电解质室温电导率达7.32×10-4S/cm,添加乙酰丙酮后,电导率可上升至10-3S/cm。体系在75℃以下稳定,较高温度下由于丙酮等溶剂挥发而使导电性能下降。PVDF-HFP/AgClO4-acetone polymer solid electrolyte was prepared and characterized with DSC, XRD and AC impedance spectroscopy. The conductivity reached to 7.32 ×10^-4S/cm at room temperature and increased to the order of 10^-3S/cm when acetylacetone was added to the PVDF-HFP/AgClO4-acetone complex system. The system was stable below 75℃. The conductivity decreased at higher temperature owing to the volatilization of solvent.
