Dynamic Hosts for High-Performance Li-S Batteries Studied by Cryogenic Transmission Electron Microscopy and in Situ X-ray Diffraction

发表刊物：Acs Energy Letters

摘要：Developing a high-performance sulfur host is central to the commercialization and general development of lithium-sulfur batteries. Here, for the first time, we propose the concept of dynamic hosts for lithium-sulfur batteries and elucidate the mechanism through which TiS2 acts in such a fashion, using in situ X-ray diffraction and cryogenic scanning transmission electron microscopy (cryo-STEM). A TiS2-S composite electrode delivered a reversible capacity of 1120 mAh g(-1) at 0.3 C after 200 cycles with a capacity retention of 97.0% and capacities of 886 and 613 mAh g(-1) at 1.0 C up to 200 and
