In Situ Synthesis of CoMoO₄ Microsphere@rGO as a Matrix for High-Performance Li-S Batteries at Room and Low Temperatures.

ABSTRACT: Lithium-sulfur batteries (Li-S batteries) have attracted wide attention due to their high theoretical energy density and the low cost of sulfur cathode material. However, the poor conductivity of the sulfur cathode, the polysulfide shuttle effect, and the slow redox kinetics severely affect their cycling performance and Coulombic efficiencies, especially under low-temperature conditions, where these effects are more exacerbated. To address these issues, this study designs and synthesizes a microspherical cobalt molybdate@reduced graphene oxide (CoMoO₄@rGO) composite material as the cathode material for Li-S batteries. By growing CoMoO₄ nanoparticles on the rGO surface, the composite material not only provides a good conductive network but also significantly enhances t
