Antimony Sulphide Nanorods Decorated onto Reduced Graphene Oxide Based Anodes for Sodium-Ion Battery

Sb2S3 and Sb2S3/rGO nanorods were developed by a facile hydrothermal route and thoroughly investigated for their crystallinity, and phase evolution using XRD, FESEM/EDS, and FTIR analysis. The electrochemical sodium-ion charge storage behavior of the synthesized anodes was examined in CR-2032 type coin cells using galvanostatic charge-discharge measurements at a current of similar to 50 mAg(-1). The preliminary galvanostatic cycling data shows that Sb2S3, and Sb2S3/rGO exhibits a decent discharge and charge capacity of similar to 601 mAhg(-1), similar to 256 mAhg(-1), 528 mAh.g(-1), and similar to 399 mAh.g(-1), respectively, for the first cycle with Coulombic efficiency similar to 42.6% and similar to 75.6%. It was found that rGO incorporation can salvage the capacity loss and improved Coulombic efficiency in the first cycle. However, the rapid capacity fades in the subsequent cycles warrant further in-depth studies to get an idea about the Na-ion storage behavior in the electrodes. (C) 2019 Elsevier Ltd.
