Two‐Step Catalytic Against Polysulfide Shuttling to Enhance Redox Conversion for Advanced Lithium–Sulfur Batteries

The development of lithium-sulfur batteries is seriously hindered by the shuttle effect of lithium polysulfides (LiPSs) and the low electrical conductivity of sulfur. To solve these problems, efficient catalysts can be used to improve the conversion rate of LiPSs and the conductivity of sulfur cathode. Herein, annealed melamine foam supported MoSe
