摘要
采用交流阻抗方法研究了微米级Al2 O3 微粒掺杂的聚环氧乙烷 (PEO) 10 _LiClO4 _Al2 O3 复合聚合物电解质体系。和 (PEO) 10 LiClO4 体系相比 ,(PEO) 10 _LiClO4 _Al2 O3 体系的室温导电率增加。同时还对交流阻抗谱图的模拟等效电路进行了讨论。
A composite polymer electrolyte of Polyethyleneoxide(PEO) 10 _LiClO 4 containing fine Al 2O 3 particles was studied by use of electrochemical impedance spectroscopy. Compared with the polymer electrolyte without Al 2O 3 particles, the room_temperature_conductivity of (PEO) 10 _LiClO 4_Al 2O 3 composite polymer electrolyte was considerably enhanced. Moreover, the equivalent circuits and the effect of direct voltage on impedance spectroscopy were discussed.
