英文摘要 | 深入研究了交替马来酸酐共聚物多缩乙二醇酯(CP350)两种锂盐络合物CP350/LiAsF_6和CP350/LiPF_6的离子传导性能,给出了与复阻抗谱相对应的等效电路.离子电导率随[Li]/[EO]的变化而出现一极大值,室温下,两体系电导率极大值分别为1.38×10(-4),8.32×10(-5)S/cm.电导率随温度升高而增加.导电行为呈非-Arrhenius特征.阴阳离子半径之和(r_c+r_a)愈大,离子电导率愈高.; A comb polymer(CP350)with oligo-oxyethylene side chains was prepared from methyl vinyl ether/maleic anhydride copolymer.The ionic conductivity of CP350/LiAsF6 and CP350/LiPF6 complexes was studied as a function of temperature and[Li]/[EO]ratios.A equivalent circuit was given to interpret complex impedance spectra. At 25℃,the ionic conductivity maxima of the two systems are 1.38×10(-4),8.32×10(-5)S/cm respectively. The appearance of the conductivity maxima has been interpreted as being due to the effect of microviscosity on ion transport. lonic conduction displays non-Arrhenius behaviour.The temperature dependence of ionic conductivity was attributed mainly to the temperature dependence of charge carrier hopping,ion pairing and micro Brown motion of side chains.The larger the(rc+ra)value the salt has,the higher the conductivity of the electrolyte film is.; 作者联系地址:中国科学院长春应用化学研究所; Author's Address: Changchun Institute of Applied Chemistry,Academia Sinica,Changchun 130022 |
