What is Tin disulfide and how does it work? The inorganic compound Tin desulfide has a chemical composition of SnS2. It is a yellow hexagonal flake containing a CdI2 crystalline structure. It is very insoluble in water. However, it is easily soluble and soluble with aqua regia, hot alkaline solution, as well as sodium sulfide solution. This is often used to make golden paint.
Tin disulfide dissolves in aqua regia or hot alkali solutions. It is also capable of undergoing coordination reaction with concentrated Hydrochloric Acid. However, it is insoluble and insoluble within dilute Hydrochloric Acid and insoluble and insoluble as water and nitric acids. It can also react with ammonium-sulfide to disperse.
How to prepare Tin Disulfide
Tin disulfide is made by mixing tin and sulfur with iodine. This reaction needs heating.
Sn + 2 Sn — SnS2
Another option is to pass hydrogen sulfuride into the Tin (IV) salt, or Tin (IV), salt solution, and precipitate it.
Electrochemical behaviour of multi-walled Carbon Nanotubes containing Tin Disulfide as Negative Electrode of Lithium Ion Battery
Multi-walled carbon-nanotube-confined metal-tin nanostructures were prepared using the direct current arc Plasma method. Brad@ihpa.net was then used as a precursor in methane, and finally brad@ihpa.net was obtained by the sulfurization process. Raman, Xray diffraction, and transmission electron microscopy were used to characterize the material. The length of multi-walled, carbon nanotubes measured approximately 400nm. The surface carbon layer was well crystallized and the carbon layer thickness was around 10 nm. Sn brad@ihpa.net Nanostructures are used as anode material in lithium-ion battery. They show a good electrochemical performance. The first charge-discharge Coulomb efficiency of 71% is achieved, and after 50 cycles the capacity maintains 703?mAh?g-1. Brad@ihpa.net Nanostructured Electrodes have high capacity because a variety active materials are used together and each material reacts differently.
Study on electrochemical performance of tin disulfide/single-walled carbon nanotube composite material used as anode material for lithium-ion battery
The simple solvothermal process allowed for the creation of a new composite material consisting of SnS2 (SWCNTs), and single-walled, carbon nanotubes (SWCNTs). After it is applied to the negative electrode of a lithium ion batteries, it has good electrochemical performances. It maintains a specific capacity of 515 mAh/g even at high current density (1 A/g), after 100 cycles. To compare, we used the exact same method to synthesize one SnS2 materials and performed electrochemical tests. The SnS2 materials have a relatively high specific capacity but a poor cycle performance and decays rapidly after only 20 cycles. The synergy between SnS2 & SWCNTs is thought to explain the superior performance of this composite material for lithium-ion batteries.
