Abstract

Herein, the concept of constructing binder- and carbon additive-free organosulfur cathode was proved based on thiol-containing conducting polymer poly(4-(thiophene-3-yl) benzenethiol) (PTBT). The PTBT featured the polythiophene-structure main chain as a highly conducting framework and the benzenethiol side chain to copolymerize with sulfur and form a crosslinked organosulfur polymer (namely S/PTBT). Meanwhile, it could be in-situ deposited on the current collector by electro-polymerization, making it a binder-free and free-standing cathode for Li-S batteries. The S/PTBT cathode exhibited a reversible capacity of around 870 mAh g at 0.1 C and improved cycling performance compared to the physically mixed cathode (namely S&PTBT). This multifunction cathode eliminated the influence of the additives (carbon/binder), making it suitable to be applied as a model electrode for operando analysis. Operando X-ray imaging revealed the remarkable effect in the suppression of polysulfides shuttle via introducing covalent bonds, paving the way for the study of the intrinsic mechanisms in Li-S batteries.

摘要

在此，基于含硫醇的导电聚合物聚（4-（噻吩-3-基）苯硫醇）（PTBT），证明了构建无粘结剂和无碳添加剂的有机硫阴极的概念。PTBT以聚噻吩结构主链作为高导电骨架，苯硫醇侧链与硫共聚形成交联有机硫聚合物（即S/PTBT）。同时，它可以通过电聚合原位沉积在集流体上，使其成为锂硫电池的无粘结剂自立式阴极。与物理混合阴极（即S&PTBT）相比，S/PTBT阴极在0.1 C时表现出约870 mAh g的可逆容量和改善的循环性能。这种多功能阴极消除了添加剂（碳/粘结剂）的影响，使其适合用作原位分析的模型电极。原位X射线成像揭示了通过引入共价键抑制多硫化物穿梭的显著效果，为锂硫电池内在机制的研究铺平了道路。
