Summary: Li-S batteries are becoming increasingly popular due to their low cost, large theoretical capacity, and high theoretical energy density. However, the strong shuttle phenomenon of lithium polysulfides has significantly reduced performance and hindered commercial applications. In this study, a novel 3D pill-structured Ti-MOF@S composite with a stable framework was developed to address these issues. The composite's stable framework prevents the collapse of the cathode structure, while the porous structure of the Ti-MOF adsorbs polysulfides to alleviate the shuttle phenomenon. When used as a cathode, the composite showed outstanding initial capacity and good reversibility.

Summary: The study investigates the impact of host material porosity on the performance of Li-S batteries using a sulfur-rich copolymer as the cathode active ingredient. Two types of porous CNF samples were designed to study the effects, and it was found that using microporous CNFs led to stable capacity over a larger number of cycles compared to mesoporous CNFs. The research highlights the significant role of cathode host porosity in battery performance, despite the positive effect of C-S bond formation in the active material.

Summary: A lithium-sulfur battery with Co3V2O8 hollow microspheres as catalyst additives is developed to address the shuttle effect caused by the dissolution of lithium polysulfides. The Co3V2O8 acts as a bifunctional additive, immobilizing the LiPS through V-S and Li-O interactions and facilitating the conversion of long-chain LiPS into short ones. The hollow microspheres also serve as a sulfur reservoir, confining more LiPS and inhibiting the shuttle effect. The Li-S cell demonstrates high initial discharge capacity, good cycle stability, and excellent rate capability.
