Summary: Lithium-sulfur batteries (LSBs) are attracting significant interest due to their high energy density and cost-effectiveness. However, the practical application of LSBs has been hindered by the presence of soluble lithium polysulfides (LiPSn) and slow conversion kinetics. In this study, Co9S8 nanoparticles with carbon nanotubes (CNTs) and pyrrole-modified graphene (Co9S8/CNTs-Gr) were synthesized, which exhibited superior electrochemical performance for sulfur fixation and LiPSn conversion. The nanoarchitecture design of Co9S8/CNTs-Gr resulted in enhanced rate performance and high catalytic activity for polysulfide conversion. The S@Co9S8/CNTs-Gr cathode showed outstanding performance, with high reversible specific capacity and good cycling stability. This work provides a delicate design for high-performance LSBs and enhances understanding of LiPSn adsorption and redox conversion.

Summary: A self-assembled lithiophilic interface (SALI) is constructed by introducing a meticulously synthesized Ni-bis(dithiolene)-based molecule (NiS4-COOH) into a hybrid fluorinated ester-ether electrolyte to regulate Li electroplating behavior. The SALI formed by NiS4-COOH molecules on the Li metal surface reduces the initial Li deposition overpotential and guides uniform Li electrodeposition. Additionally, the NiS4-COOH additive changes the ionic coordination environment in the electrolyte, suppressing PF6- decomposition and optimizing SEI composition, leading to impressive electrochemical performance in Li-ion batteries.
