High Electrochemical Performance of Nanotube Structured ZnS as Anode Material for Lithium–Ion Batteries

Abstract

By using ZnO nanorods as an ideal sacrificial template, one-dimensional (1-D) ZnS nanotubes with a mean diameter of 10 nm were successfully synthesized by hydrothermal method. The phase composition and microstructure of the ZnS nanotubes were characterized by using XRD (X-ray diffraction), SEM (scanning electron micrograph), and TEM (transmission electronic microscopy) analysis. X-ray photoelectron spectroscopy (XPS) and nitrogen sorption isotherms measurements were also used to study the information on the surface chemical compositions and specific surface area of the sample. The prepared ZnS nanotubes were used as anode materials in lithium-ion batteries. Results show that the ZnS nanotubes deliver an impressive prime discharge capacity as high as 950 mAh/g. The ZnS nanotubes also exhibit an enhanced cyclic performance. Even after 100 charge/discharge cycles, the discharge capacity could still remain at 450 mAh/g. Moreover, cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) measurements were also carried out to evaluate the ZnS electrodes.

Review and Outlook of Zinc Sulfide Nanostructures for Supercapacitors

“…Besides, pure ZnS suffers from volume expansion during the charge/discharge cycle and poor cyclic and rate performance. 87 On the other hand, ZnS performed well as corrosion inhibiter in 1 M HCl for mild steel. 88 ZnS has tremendous potential for supercapacitors because of its tunable electronic properties and high thermal and rich redox kinetics.…”

Green synthesis of carbon-supported ultrafine ZnS nanoparticles for superior lithium-ion batteries

“…Additionally, previous research has indicated that ZnS undergoes a combined conversion-alloying reaction during cycling, resulting in a large irreversible volume change. 6 Numerous efforts have been dedicated to enhancing the lithium storage performance of ZnS, employing various strategies such as nanostructural design, 7 heterostructure building 8 and combination with carbonaceous materials. 9 Prominently, the modification of nanoscale ZnS with a carbon matrix has shown great promise in mitigating the pulverization process during cycling.…”

Synthesis of core–shell ZnS@C microrods as advanced anode materials for lithium-ion batteries

“…[33][34][35][36] For example, Zhang et al prepared ZnS nanotubes using ZnO nanorods as a template, which exhibit a capacity of 950 mA h g À1 at 0.1 A g À1 and good cycling performance when evaluated as anodes for LIBs. 37 Compared to the rational structure design, the hybridization with conductive carbonaceous materials was considered as more effective and wider used strategy for enhancing the electrochemical performance of the ZnS anode. [38][39][40][41] For example, Liu et al prepared pitaya-like ZnS/ carbon nanospheres as a LIB anode, which benefitted from the dual-carbon being able to accommodate the volume expansion in the cycling process.…”
