随着能源危机和环境问题的日益严峻，锂离子电池成为当今世界极具发展潜力的新型绿色化学电源。相对于传统锂离子二次电池，锂硫电池具有高比容量、高能量密度、环境友好等优点，被公认是下一代锂离子电池的最佳候选。目前，锂硫电池仍存在一些问题尚未解决，例如单质硫导电性差，多硫化物溶解和穿梭效应，金属锂电极稳定性差等，严重影响了锂硫电池的实际应用。本项目针对锂硫电池自身特点和目前存在问题，以传统的沸石分子筛和金属有机框架等微孔材料为研究对象，研究其在锂硫电池正极材料和复合隔膜材料等关键基础材料方面的应用，微孔材料作为硫载体，增强正极材料和多硫化物的分子间作用力；利用微孔材料作为复合隔膜材料，有效降低多硫化物的穿梭效应，从而有效提高锂硫电池的性能和循环稳定性，为锂硫电池的实际应用提供研究数据。

With the increasingly serious energy crisis and environmental problems, the lithium ion battery become the world's new green chemical power source. Compared with traditional lithium ion battery, lithium-sulfur battery has advantages of high energy density, environment friendly and was recognized as the best candidate for the next-generation lithium-ion batteries. At present, lithium sulfur batteries still have some unsolved problems, such as poor electrical conductivity of elemental sulfur, polysulphide dissolving and Shuttle effect, poor stability of metallic lithium electrode, all of which were serious impact on the practical application of lithium sulfur batteries. This project study the performance improvement of cathode and composite membrane of lithium-sulfur battery based on microporous materials including traditional zeolite and metal organic framework. For the cathode of lithium sulfur batteries, the microporous materials can serve as carrier and precursors to fabricate of porous carbon materials for the sulfur. For the membrane materials of lithium sulfur batteries, the microporous materials can serve as obstacle for the polysulphide and effectively reduce the shuttle effect of polysulfide. Thus effectively improve the performance of lithium sulfur batteries and cycle stability, provide research data for the practical application of lithium sulfur batteries.
