摘要：Shuttle effect,poor conductivity and large volume expansion are the main factors that hinder the practical application of sulfur ***,rational structure designing of carbon-based sulfur hosts is the most effective strategy to address the above ***,the preparation process of carbon-based sulfur hosts is usually complex and ***,it is necessary to develop an efficient and cost-effective method to fabricate carbon hosts for high-performance sulfur ***,we reported the fabrication of a bio-derived nitrogen doped porous carbon materials(BNPC)via a molten-salt method for high performance sulfur *** long-range-ordered honeycomb structure of BNPC is favorable for the trapping of polysulfide(PS)species and accommodates the volumetric variation of sulfur during cycling,while the high graphitization degree of BNPC favors the redox kinetics of sulfur ***,the nitrogen doping content not only enhances the electrical conductivity of BNPC,but also provides ample anchoring sites for the immobilization of PS,which plays a key role in suppressing the shuttle *** a result,the S@BNPC cathode exhibits a high initial specific capacity of 1189.4 mA·h/g at *** 300 cycles,S@BNPC still maintains a capacity of 703.2 mA·h/g which corresponds to a fading rate of 0.13%per cycle after the second *** work offers vast opportunities for the large-scale application of high performance carbon-based sulfur hosts.
