The Synergistic Catalytic Effect of 2D Ultrathin Fe <sub>2</sub> O <sub>3</sub> ‐Fe <sub>3</sub> O <sub>4</sub> Heterointerface on Lithium Polysulfides
The practical application of the sulfur cathode in lithium–sulfur (Li–S) batteries mainly depends on the suppression of lithium polysulfide (LiPSs) diffusion and the improvement...
