摘要
采用差示扫描量热法 (DSC)和交流阻抗方法对EC增塑的 (PEO) 16 LiClO4 聚电解质进行了研究。结果表明 (PEO) 16 LiClO4 /EC体系的玻璃化转变温度 (tg)及PEO的结晶度 (Xc)降低 ,电导率 (б)增加 ,且б与温度 (T)的关系符合Arrhenius行为。提出了离子导电聚电解质 /不锈钢 (SS)
The Polyethylene oxide(PEO) 16 LiClO 4 polymer electrolyte plasiticized with EC was studied using Differential Scanning Calorimetry(DSC)and impedance spectroscopy.It is found that the conductivity of the plasticized films were increased and the temperature dependence of the conductivity is Arrhenius like.Moreover,a schematic of the electrical double layer and an equivalent circuit relative to the SS/polymer electrolyte/SS structure were proposed.
