This study utilizes metal sulfide MoS2 as catalysts in lithium-sulfur batteries, improving their capacity and cycling performance. The presence of metal sulfide accelerates the conversion of polysulfides and enhances electronic conductivity.
Lithium-sulfur batteries have promise as next-generation energy storage device due to their high capacity and energy density. However, their wide application is faced with great challenges, in particular the polysulfide migration and poor electronic conductivity during the electrochemical cycles. Herein, we report the employment of metal sulfide MoS2 as catalysts to promote the polysulfide conversion. When used as cathode materials in Li-S batteries, the electrochemical results indicate that the MoS2/S cathode delivers high specific capacity and stable cycling performance. The excellent electrochemical performance is attributed to the presence of the metal sulfide, which could accelerate the polysulfide conversion and improve the whole electronic conductivity. This work provides new insights to enhance the electrochemical performance by using metal sulfide as sulfur matrix for high-performance lithium-sulfur batteries.
