One-Dimensional Rod-Like Sb₂S₃-Based Anode for High-Performance Sodium-Ion Batteries

Abstract

Due to the high theoretical capacity of 946 mAh g(-1), Sb2S3 can be employed as promising electrode material for sodium-ion batteries (SIBs). Herein, the sodium storage behaviors of one-dimensional (1D) Sb2S3-based materials (Sb2S3 and Sb2S3@C rods) are successfully studied for the first time, displaying good cyclability and rate capability owing to their unique morphology and structure. Specifically, the Sb2S3@C rods electrode presents greatly enhanced electrochemical properties, resulting from the introduction of thin carbon layers which can effectively alleviate the strain caused by the large volume change and simultaneously improve the conductivity of electrode during cycling. At a current density of 100 mA g(-1), it delivers a high capacity of 699.1 mAh g(-1) after 100 cycles, which corresponds to 95.7% of the initial reversible capacity. Even at a high current density of 3200 mA g(-1), the capacity can still reach 429 mAh g(-1). This achievement may be a significant exploration for develpoing novel 1D Sb-based materials or metal sulfide SIBs anodes.

Recent Advances in Sodium-Ion Battery Materials

“…An ultralong worm-like MoS 2 was also reported by Xu et al (Figure 9a, e) [196]. Tin-based sulfides (SnS [197][198][199][200]) and SnS 2 [201,202]) and antimony sulfide (Sb 2 S 3 [203][204][205][206][207]) have attracted considerable attention due to the conversion/alloying reactions, in which Sn and Sb can alloy with Na + to show electrochemical reactivity. Cao and co-workers have reported SnS@ reduced graphene oxide composites with SnS nanoparticles anchored on the surface of graphene, and the composites exhibited a reversible capacity of 457 mAh g −1 with stable cycle life [208].…”

[125] 1D rod-like Sb 2 S 3 -based materials (Sb 2 S 3 and Sb 2 S 3 @C) with abundant space in the haystack-like architecture (Figure 6a,b) was reported by Hou et al [124] The unique rod structure can offer numerous active sites for (de)sodiation and shorten the diffusion pathways for electrons and Na ions effectively.

Enhanced Visible-light Response and Conductivity of the TiO2/reduced graphene oxide/Sb2S3 Heterojunction for Photoelectrochemical Water Oxidation

“…The annealing process is not necessary for making the rutile TiO 2 but is important to improve the degree of the crystallinity for the rutile TiO 2 [25]. In addition, all of the Sb 2 S 3 peaks (JCPDS 42-1393) [26] are observed in the pattern for the Sb 2 S 3 powder, and the primary two peaks at the 2 theta values of 29.4 and 32.4 for the Sb 2 S 3 were clearly obtained in the patterns for the TiO 2 /Sb 2 S 3 and TiO 2 /rGO/Sb 2 S 3 electrodes, suggesting the successful incorporation of the Sb 2 S 3 nanoparticles in the TiO 2 /Sb 2 S 3 and TiO 2 /rGO/Sb 2 S 3 electrodes. However, there is no peak for the rGO nanomaterial in the pattern for the TiO 2 /rGO/Sb 2 S 3 electrode.…”
