主　　题：Electrospinning ZnS Carbon fbers Porous Lithium storage 

摘      要：ZnS is a promising material for lithium-ion battery anodes due to its abundant natural resources,simplicity of synthesis,and high theoretical lithium storage ***,it needs to be optimized for its low conductivity and volume efect during the charge–discharge *** traditional method of combining with carbonaceous materials is usually laborious,and the required sulfuration process may possibly result in the destruction of materials *** this study,hybrid materials formed by the combination of ZnS nanocrystals and high porosity carbon fbers were synthesized by one-step electrospinning using zinc diethyldithiocarbamate and polyacrylonitrile as raw materials and poly(ethylene glycol)—block-poly(propylene glycol)—block-poly(ethylene glycol)as *** method is simple and avoids the infuence of sulfuration process on the morphology of *** composite presents a specifc capacity of 592.2 mAh g^(−1) under a current density of 1 A g^(−1) after 1000 *** porous structure signifcantly decreases the difusion mean-free path of Li+and inhibits the volume efect associated with the lithium storage process of *** addition,the 3D cross-linked carbon fbers improve the conductivity of *** study can serve as an inspiration for the development of other lithium storage composites.
