Sodium-ion batteries (SIBs) have emerged as a promising alternative for energy storage. In this work, it has been synthesized a nanocomposite material of SbxSbySz/Carbon nanofibers (CNFs) using low-cost synthesizing methods. First, CNFs have been obtained by electrospinning method with subsequent carbonation at 700 degrees C. Afterward, a SbxSbySz thin coating is deposited on the CNFs by chemical bath deposition technique to obtain the SbxSbySz/CNFs. In order to obtain the SnSb2S4 crystalline phase, the composite is heated at 300 degrees C in nitrogen atmosphere. The evaluation of this nanocomposite as the anode for SIBs has a reversible discharge capacity of 180 mAh g(-1) and a columbic efficiency of 61.4% after 9 cycles. On the other hand, the resistance associated to the charge transfer to the CNFs decreases from 115.03 omega to 77.86 omega due to the incorporation of SnxSbySz. Finally, an easy and inexpensive route has been proposed for the synthesis of SbxSbySz/CNFs composite with great potential to be used as anode material for SIBs.
