Sulfur–amine chemistry-based synthesis of multi-walled carbon nanotube–sulfur composites for high performance Li–S batteries

Abstract

We report a sulfur–amine chemistry-based method to prepare multi-walled carbon nanotube–sulfur (MWNT–S) composites in a highly efficient and quantitative manner. The resulting MWNT–S composites exhibit excellent cycling stability at up to 400 cycles, with high sulfur loading. Developing this method also increases the number of research routes that could be pursued with respect to Li–S batteries.
