聚合物电解质材料已经成为当前锂离子电池研究领域的热点之一。复合化是有效提高聚合物电解质材料性能的有效手段。本文从纳米粒子掺杂的角度,综述了近年来无机纳米粒子对复合聚合物电解质(CPE)体系的离子电导率、锂离子迁移数的影响,并介绍了四种初步解释了无机纳米粒子在复合聚合物电解质中的作用的机理;讨论了无机纳米粒子对CPE体系/电极界面稳定及相容性的影响;提出了无机纳米粒子掺杂的复合聚合物电解质研究的三个热点方向。
Polymer electrolyte materials have become one of the hot topics in current lithium ion battery research field. Compounding is an effective means to effectively improve the performance of polymer electrolyte materials. In this paper, from the perspective of the doping of nanoparticles, the effects of inorganic nanoparticles on the ionic conductivity and the number of lithium ions migration of the composite polymer electrolyte (CPE) system are reviewed. In addition, four kinds of preliminary explanations of the effects of inorganic nanoparticles on the composite The mechanism of action of inorganic nanoparticles on the stability and compatibility of CPE system / electrode interface was discussed. Three hot spots directions for the research on composite polymer electrolyte doped with inorganic nanoparticles were proposed.
