无机纳米粒子在复合聚合物电解质中作用的研究进展

Progress in the Study on the Effect of Inorganic Nano-particles in Composite Polymer Electrolytes

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 electrolytes have become one of the hot point in the research of lithium ion batteries at present. In this paper the effect of inorganic nano-particles on the composite polymer electrolytes （CPE） is reviewed. Four different models are applied to explain the improvements of ionic conductivity and lithium ion transference number that can be attributed to the additions of inorganic nano particles. The effect of inorganic nano-particles on the properties of CPE/ electrode interface is also discussed.
