The self-assembled structure has a significant impact on the performance of ion conductors. We prepared a new type of electrolyte with self-assembled structures from an azobenzene-based liquid crystalline (LC) monomer and its corresponding polymer. By doping different amounts of monomers and lithium salt LiTFSI, the self-assembled nanostructure of the electrolyte was changed from lamellae to double gyroid. The ionic conductivity of the azobenzene-based electrolytes with the double gyroid structure was 1.64 × 10 S cm, higher than most PEO-based polymer electrolytes. The azobenzene-based system provides a new strategy to design solid electrolytes with self-assembled structures that may be potentially used in solid-state lithium-ion batteries.
自组装结构对离子导体的性能有重大影响。我们用一种基于偶氮苯的液晶（LC）单体及其相应聚合物制备了一种具有自组装结构的新型电解质。通过掺杂不同量的单体和锂盐LiTFSI，电解质的自组装纳米结构从片层转变为双连续螺旋状。具有双连续螺旋状结构的基于偶氮苯的电解质的离子电导率为1.64×10 S cm，高于大多数基于聚环氧乙烷（PEO）的聚合物电解质。基于偶氮苯的体系为设计具有自组装结构的固体电解质提供了一种新策略，这种电解质可能潜在地应用于固态锂离子电池。
