英文摘要	The metal sulfide-carbon nanocomposite is a new class of anode material for sodium ion batteries, but its development is restricted by its relative poor rate ability and cyclic stability. Herein, we report the use of double-helix structure of carrageenan-metal hydrogels for the synthesis of 3D metal sulfide (MxSy) nanostructure/carbon aerogels (CAs) for high-performance sodium-ion storage. The method is unique, and can be used to make multiple MxSy/CAs (such as FeS/CA, Co9S8/CA, Ni3S4/CA, CuS/CA, ZnS/CA, and CdS/CA) with ultra-small nanoparticles and hierarchical porous structure by pyrolyzing the carrageenan-metal hydrogels. The as-prepared FeS/CA exhibits a high reversible capacity and excellent cycling stability (280mAh(-1) at 0.5Ag(-1) over 200cycles) and rate performance (222mAh(-1) at 5Ag(-1)) when used as the anode material for sodium-ion batteries. The work shows the value of biomass-derived metal sulfide-carbon heterostuctures in sodium-ion storage.; National Natural Science Foundation of China [51473081, 51672143, 51671003]; National Key Research and Development Program of China [2016YFB0100201]; South China University of Technology (SCUT); Fundamental Research Funds for the Central Universities from SCUT; SCI(E); ARTICLE; d.yang@qdu.edu.cn; xiayz@qdu.edu.cn; guosj@pku.edu.cn; 51; 15925-15928; 55
