Modulating of MoSe2 functional plane via doping-defect engineering strategy for the development of conductive and electrocatalytic mediators in Li-S batteries
文献摘要：
The lithium polysulfide shuttle and sluggish sulfur reaction kinetics still pose significant challenges to lithium-sulfur(Li-S)batteries.The functional plane of Fe-MoSe2@rGO nanohybrid with abundant defects has been designed and applied in Li-S batteries to develop the functional separator and multi-layer sulfur cathode.The cell with a functional separator exhibits a retention capacity of 462 mAh g-1 after the 1000th at 0.5 C and 516 mAh g-1 after the 600th at 0.3 C.Even at low electrolyte conditions(7.0 μL mgsulfur-1 and 15 μL mgsulfur-1)under high sulfur loadings(3.46 mg cm-2 and 3.73 mg cm-2),the cell still presents high reversible discharge capacities 679 and 762 mAh g-1 after 70 cycles,respectively.Further,at sulfur loadings up to 8.26 and 5.2 mg cm-2,the cells assembled with the bi-layers sulfur cath-ode and the tri-layers sulfur cathode give reversible capacities of 3.3 mAh cm-2 after the 100th cycle and 3.0 mAh cm-2 after the 120th cycle,respectively.This research not only demonstrates that the Fe-MoSe2@rGO functional plane is successfully designed and applied in Li-S batteries with superior electro-chemical performances but also paves the novel way for developing a unique multi-layer cathode tech-nique to enhance and advance the electrochemical behavior of Li-S cells at a high-sulfur-loading cathode under lean electrolyte/sulfur(E/S)ratio.
