【Abstract】 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.更多还原
