MnO₂/rGO/CNTs Framework as a Sulfur Host for High-Performance Li-S Batteries.

ABSTRACT: Lithium-sulfur batteries are very promising next-generation energy storage batteries due to their high theoretical specific capacity. However, the shuttle effect of lithium-sulfur batteries is one of the important bottlenecks that limits its rapid development. Herein, physical and chemical dual adsorption of lithium polysulfides are achieved by designing a novel framework structure consisting of MnO₂, reduced graphene oxide (rGO), and carbon nanotubes (CNTs). The framework-structure composite of MnO₂/rGO/CNTs is prepared by a simple hydrothermal method. The framework exhibits a uniform and abundant mesoporous structure (concentrating in ~12 nm). MnO₂ is an α phase structure and the α-MnO₂ also has a significant effect on the adsorption of lithium
