摘要：

New plasticized polymer electrolytes were synthesized based on poly ethylene oxide (PEO), Poly (NN-dimethylamino-ethyl -methacrylate) (PDMAEMA), LiN(CF3SO2)(2) (LITFSI) as the salt and tetraethylene glycol dimethyl ether(tetraglyme) and EC + PC as plasticizers. The preparation and characterization of the polymer electrolytes were investigated as a function of temperature and various concentrations of LITFSI. Impedance spectroscopy and differential scanning calorimeter (DSC) were used to characterize the effects of various temperature, lithium salt concentration and two plasticizers on conductivity. The complex of PDMAEMA/PEO/LiTFSI/tetraglyme (S2) exhibits higher conductivity (4.74 x 10(-4) S cm(-1) 2degreesC) than PDMAEMA/PEO/LiTFSI/EC + PC (SI). (C) 2004 Elsevier Ltd. All rights reserved.
