A Sulfur-Rich Copolymer@CNT Hybrid Cathode with Dual-Confinement of Polysulfides for High-Performance Lithium-Sulfur Batteries.

A sulfur-rich copolymer@carbon nanotubes hybrid cathode is introduced for lithium-sulfur batteries produced by combining the physical and chemical confinement of polysulfides. The binderfree and metal-current-collector-free cathode of dual confinement enables an efficient pathway for the fabrication of high-performance sulfur copolymer carbon matrix electrodes for lithium-sulfur batteries.
