摘要：Rationally designing sulfur hosts with the functions of confining lithium polysulfides(LiPSs)and promoting sulfur reaction kinetics is critically important to the real implementation of lithium-sulfur(Li-S)***,the defect-rich carbon black(CB)as sulfur host was successfully constructed through a rationally regulated defect ***-obtained defect-rich CB can act as an active electrocatalyst to enable the sulfur redox reaction kinetics,which could be regarded as effective inhibitor to alleviate the LiPS *** expected,the cathode consisting of sulfur and defect-rich CB presents a high rate capacity of 783.8 mA·h·g^−1 at 4 C and a low capacity decay of only 0.07% per cycle at 2 C over 500 cycles,showing favorable electrochemical *** strategy in this investigation paves a promising way to the design of active electrocatalysts for realizing commercially viable Li-S batteries.
