MoS2 anchored carbon nitride based mesoporous material as a polysulfide barrier for high capacity lithium-sulfur battery
Molybdenum disulfide (MoS2) 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/MoS2 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/MoS2 in comparison with the bare CN is attributed to anchored MoS2 which can change the structural, physiochemical and increased electrochemical active surface area of CN/MoS2 based hybrid.
