柔性聚苯胺与碳质材料协同改性锂硫电池正极研究进展

Research Progress in Flexible Polyaniline and Carbon-based Materials Co-modified as Cathode Materials for Lithium-sulfur Batteries

锂硫电池具有高能量密度、低成本和环境友好等特点,被认为是最具潜力的下一代储能体系之一。介绍了柔性导电聚苯胺与碳质材料协同改性锂硫电池正极材料方面的研究进展,并与传统的聚苯胺或碳质材料单独改性硫基正极材料进行对比。围绕后者在单独改性中存在的电化学性能不佳的问题,对柔性导电聚苯胺与碳质材料二元复合改性硫基正极材料的结构设计和制备方法等进行综述,并对其未来发展方向和商业化应用进行展望。

Li-S battery(Li-S) is considered as one of the most promising battery candidate in the next-generation energy storage systems by virtue of its high theoretical energy density, low cost and environmental compatibility. This work systematically introduced the state-of-art cathode materials with co-modification of polyaniline and carbon materials for Li-S batteries, as compared with the those cathodes individually decorated with either polyaniline or carbon materials. Aimed at the intrinsic drawbacks, substantial research progresses were detailedly summarized. Furthermore, the structural design and preparing processes of the co-modified sulfur cathodes and their potential commercialization were illustrated.
