“…Secondly, there is the surface/interface modulation, where the interconversion of Li 2 S and polysulfides corresponds to the charging/discharging process of LiÀ S batteries, where the slow kinetic conversion of polysulfides inhibits the capacity of LiÀ S batteries. Surface/interface modulation of the catalyst can accelerate charge transfer and ionic conduction, and speed up the process of polysulfides redox [115] Copyright 2023, Elsevier B.V. (b) 0.25 g.

“…materials to improve their performance. [118][119] Wang et al [115] proposed a simple strategy to modify one-dimensional material VS 4 into two-dimensional layered material using anionic surfactant PVP, and then grow vertically on the MoS 2 surface to form a heterogeneous structure (Figure 7(c)). According to Figures 7(a) and (b), the presence or absence of surfactants can affect the morphology of the material structure.…”

The commercialization of Li−S batteries is seriously hindered by polysulfides with severe shuttle effect, and the inherent insulating properties and slow reaction kinetics of insoluble Li2S products. Transition metal sulfides (TMSs) have a high adsorption capacity for polysulfides and have been shown to have a strong catalytic effect on polysulfide conversion reactions. This paper reviews the research on the application of Unary TMSs, heterostructures, etc. in Li−S batteries, and gives some research methods for TMD catalysts in Li−S batteries. Finally, it points out the main focuses and direction of future Li−S battery research and development. It aims to provide some insights into the design and manufacture of advanced Li−S batteries for commercial use.
