英文摘要Iron sulfide has stood out from various anode materials on account of its high capacity, low price and environment friendliness. In practice, however, the critical obstacles of iron sulfide limit its practical application, including poor intrinsic conductivity, volume expansion and polysulfide dissolution during charge and discharge. Herein, the carbon-coated Fe1-xS composite with unique interconnected carbon matrices (Fe1-xS@C NW) was successfully synthesized via a facile one-step in situ thermal condensation method, which is intended to improve the conductivity of iron sulfide anode. In this composite, Fe1-xS is surrounded by unique interconnected carbon matrices to facilitate lithium ion diffusion and electron transport. Compared with Fe1-xS@C and Fe1-xS anode, the as-synthesized Fe1-xS@C NW anode exhibits high-rate performance (with a reversible capacity of 446 mAh g(- 1) even at 4 A g(- 1)) and low Rct value (58.2 ohm). The combination of unique interconnected carbon matrices and Fe1-xS may be responsible for the superior rate performance and low Rct of Fe1-xS@C NW anode.
