Tuned tin chalcogenides rooted in hierarchical porous carbon(HPC)with N-carbon coating layers are prepared by thermal shock under various temperatures(denoted as HPC-SnS2-PAN-Various T).With the increase of annealing temperature,the morphology and phase structure of SnS2,as well as the cyclization degree of polyacrylonitrile(PAN),are significantly changed,which leads to the formation of rod-like SnS and ordered structure of conductive N-carbon layer.By combining HPC,N-carbon coating derived from the cyclization of PAN,with 1D SnS nanorods generated from structural phase transformation of SnS2,the optimized composite(HPC-SnS2-PAN-500)as anode for lithium ion batteries(LIBs)provides buffer space for volume changes during alloying/dealloying process,builds a highly conductive network as well as decreases irreversible capacity from solid electrolyte interphase and enhances the ion/electron transport.Attributed to the above merits from composition regulation and architecture modification by sulfur depletion and PAN cyclization,this target anode exhibits an extraordinary cycling stability with a high specific capacity of 652.5 mA h/g at 0.5 A/g after 900 cycles.It suggests that rod-like SnS embedded in HPC with cyclized PAN layers by thermal treatment approach renders a potential structural design of anode materials for LIBs.
