In this research we will first synthesize polymers that exhibit solid electrolyte properties when complexed with lithium salts. These polymers could potentially be used as solid electrolytes in solid state lithium or lithium ion batteries. However, a major drawback of these materials is that they tend to flow under pressure when assembled in cells. As a means of increasing the mechanical properties of these polymers we plan to sandwich them in between the layers of molybdenum diselenide, tin disulfide and titanium disulfide. The synthetic methodology would first and foremost, involve insertion of lithium ions into the layered systems, followed by exfoliation in a solvent. Addition of solutions of the polymers to the exfoliated layers would lead to intercalated materials that could potentially be used in battery applications.

在这项研究中，我们将首先合成与锂盐复合时表现出固体电解质特性的聚合物。这些聚合物有可能用作固态锂或锂离子电池中的固体电解质。然而，这些材料的一个主要缺点是，当它们组装在电池中时，它们往往会在压力下流动。作为提高这些聚合物机械性能的一种方法，我们计划将它们夹在二硒化钼、二硫化锡和二硫化钛层之间。合成方法首先是将锂离子插入层状系统中，然后在溶剂中剥离。将聚合物溶液添加到剥离层中将产生可用于电池应用的插层材料。
