“…S6, † the cycling performance of the Sb 2 S 3 /SnO 2 @rGO composite is still remarkable. 21,[40][41][42][43][44][45][46] Besides, the morphology of the Sb 2 S 3 /SnO 2 @rGO electrode after 2000 cycles at 3 A g −1 has also been recorded using scanning electron microscopy. As shown in Fig.…”

Antimony Sulfide-Based Materials for Electrochemical Energy Conversion and Storage: Advances, Challenges, and Prospects

“…Obviously, carbon-loading contents play important roles in the fabrication of high-performance electrodes. For Sb 2 S 3 @NHPC, Sb 2 S 3 particles were uniformly adsorbed in the pores of NHPC, effectively avoiding the aggregation of active materials, thus delivering the reversible capacity of 600 mAh g –1 at 0.1 A g –1 . Moreover, Li + -diffusion pathways were shortened by incorporating natural stibnite with porous carbon, contributing to the improvement of electrochemical performances. , Carbon dots, as a novel class of carbon nanomaterials, exhibit a series of merits (containing ultrasmall size below 10 nm, rich surface functional groups, and low cost), significantly enhancing energy-storage properties of electroactive materials. − From Xiang’s report, the chemical bond (Sb–O–C) induced by CDs was successfully established at material heterointerfaces, which could facilitate ion shuttling and improve electrical conductivity.…”

Amorphous C/SbSx composites from natural stibnite as low cost and high performance lithium/sodium-ion battery anodes

“…However, the applications of natural stibnite in batteries are limited due to its large particle size and the challenges associated with nanometerization. Although previous methods to improve the performance of natural Sb 2 S 3 particles, such as ball milling, 17 melting with carbon materials, 10,18 carbon coating 19 and vapor transport deposition, 5 have some advantages, they also have some drawbacks. The main problems are that the carbon materials and equipment are expensive and the improvements of electrochemical performance are limited.…”
