摘要： 以丙烯腈(AN)、丙烯酸甲酯(MA)和衣康酸锂(IALi)为自由基共聚反应的主要单体, 采用溶液聚合方法, 合成轻度交联的P(AN-MA-IALi)聚合物电解质膜.通过FTIR, DSC和SEM等测试方法对共聚物的结构进行了表征, 利用交流阻抗等电化学方法对该膜的导电性能进行了研究.实验结果表明, 所制备的交联聚合物的室温电导率达到10-5~10-4 S/cm, 当IALi的质量分数为3%时, 所制备的聚合物电解质膜的电导率最大可达到1.89×10-4 S/cm.

Abstract: As the novel polymer electrolyte membrane, crosslinked P(AN-MA-IALi) was synthesized with monormers such as acrylonictrile(AN), methyl acrylate(MA) and itaconic acid lithium(IALi) via solution co-polymerization method. The molecular structure was characterized by means of FTIR, DSC and SEM. The electrochemical performance of polymer electrolyte membrane was studied by AC impedance. The results show that the conductivity of crosslinked P(AN-MA-IALi) based gel polymer electrolyte membrane could get to 10-5—10-4 S/cm measured at room temperature. The highest conductivity was 1.89×10-4 S/cm when the mass fraction of IALi was 3%.

Key words: Gel polymer electrolyte, Poly(AN-MA-IALi), Solution co-polymerization, Ionic conductivity, Lithium ion battery
