Abstract:

The organic-inorganic composite solid electrolyte not only has the advantages of polymer electrolyte with high flexibility and interface compatibility, but also possesses the merits of improved ionic conductivity and mechanical properties. However, it is difficult to construct a highly dispersive system for the preparation of such composite electrolytes, and it is also a great challenge to regulate the interfacial percolation structure of inorganic fillers with strong molecular interaction. Chemical modification or in-situ synthesis of inorganic fillers by functional organosilane is an effective strategy to solve the problems mentioned above. In this review, the research progress of using functional organosilane for organic-inorganic composite solid electrolytes through surface modification, in-situ synthesis of inorganic fillers, as cross-linking center, or preparation of ionogel based composite solid electrolytes are summarized in detail. The relationship between the organosilane functionalized fillers and the structure/properties of solid electrolytes are disclosed. Finally, the future application of functional organosilane in organic-inorganic composite solid electrolytes is summarized and prospected.

Key words: organic-inorganic composite solid electrolyte, functional organosilane, nano-filler, surface modification, in situ synthesis, ionogels

摘要:

有机-无机复合固态电解质不仅具有聚合物电解质的柔韧性和界面相容性,还能显著提高离子传导性和力学性能。然而,构建良好的填料/聚合物分散体系是制备此类复合电解质的难点,设计新型有强相互作用的功能化填料以调控界面渗流结构也面临巨大挑战。通过功能硅烷对无机填料进行化学键联改性或原位合成是解决无机填料与聚合物间分散性和界面相容性问题的有效策略。本文综述了在复合固态电解质中利用功能硅烷对无机填料进行表面改性和原位合成、功能硅烷作为复合固态电解质的交联中心和制备离子胶类复合固态电解质四方面的研究进展,重点阐述了硅烷功能化填料与固态电解质结构和性能之间的关系。最后对功能硅烷在有机-无机复合固态电解质中的应用研究进行了总结和展望。
