Incorporating Sulfur Inside the Pores of Carbons for Advanced Lithium–Sulfur Batteries: An Electrolysis Approach

We have developed an electrolysis approach that allows effective and uniform incorporation of sulfur inside the micropores of carbon nanosheets for advanced lithium–sulfur batteries. The sulfur–carbon hybrid can be prepared with a 70 wt % sulfur loading, in which no nonconductive sulfur agglomeratio...

Summary:We have developed an electrolysis approach that allows effective and uniform incorporation of sulfur inside the micropores of carbon nanosheets for advanced lithium–sulfur batteries. The sulfur–carbon hybrid can be prepared with a 70 wt % sulfur loading, in which no nonconductive sulfur agglomerations are formed. Because the incorporated sulfur is electrically connected to the carbon matrix in nature, the hybrid cathode shows excellent electrochemical performance, including a high reversible capacity, good rate capability, and good cycling stability, as compared to one prepared using the popular melt-diffusion method.
