摘要
对聚合物电解质(PE)的研究主要包括两个方面:第一,在保持聚合物电解质机械强度的前提下提高其室温离子迁移性(包括离子电导率和锂离子迁移数);第二,改善聚合物电解质与电极,特别是与锂电极的界面相容性,即在降低锂电极/聚合物电解质(Li/PE)初始界面阻抗的同时增强其界面稳定性。改善Li/PE界面相容性对于锂聚合物蓄电池的商业化具有重要意义。综述了Li/PE界面研究特点及Li/PE界面研究的最新进展。
It mainly includes two aspects for the research of polymer electrolyte （PE）： First is the enhancement of self-performance, i.e., improving the ability of ion transfer （including ionic conductivity and Li^＋ transference number） at room temperature in the case of good mechanical strength; Second is the improvement of the interfacial compatibility with electrodes, especially with lithium electrode, i.e., enhancing the interfacial stability between lithium electrode and polymer electrolyte （Li / PE） on the condition of reducing initial interfacial resistance. It is of significance for the commercialization of lithium polymer secondary batteries to improve the interracial compatibility between Li / PE. In this paper, the general features on the research of Li / PE interface were introduced, and the progresses on the research of the interfacial compatibility between Li/PE were reviewed
