MoS2 anchored carbon nitride based mesoporous material as a polysulfide barrier for high capacity lithium-sulfur battery

Abstract Molybdenum disulfide (MoS 2 ) anchored carbon nitride (CN) based nanomaterial have been developed by using the hydrothermal method, which confines sulfur on to the CN and is utilized as a sulfur host for Li-Sulfur (Li S) battery. The prepared material CN/MoS 2 demonstrated enhanced electrochemical performance with an initial charge-discharge capacity of 1252 mAh g −1 and 1264 mAh g −1 at 0.5C rate, with a reversible capacity of 680 mAh g −1 after 200 cycles. The enhanced capacity and cyclic stability for CN/MoS 2 in comparison with the bare CN is attributed to anchored MoS 2 which can change the structural, physiochemical and increased electrochemical active surface area of CN/MoS 2 based hybrid.
