What is Tin disulfide

What's Tin disulfide?

Tin disulfide (also known as Tin) is an inorganic compound that has chemical formula SnS2. It is the yellow hexagonal flake which has an CdI2 Crystal structure. It is hardly soluble in water, but it is soluble in aqua regia and hot alkaline solutions. It is as well in sodium sulfide Solution, which is often used as gold paint.

Tin disulfide will dissolve in the hot alkali solution. It is also able to undergo coordination reactions when exposed to concentrated hydrochloric acid. However, it's dissolvable in dilute hydrochloric acid and insoluble when mixed with water and nitric acid. It may also react when mixed with ammonium to dissolve.

How do I prepare the tin disulfide?

Tin disulfide is made through the direct combination of tin with sulfur in the presence of iodine. The reaction involves heating:

2. S --- SnS2

Another method is to put hydrogen sulfide through the solution of either tin (IV) salt solution or the tin (IV) salt solution and the precipitate.

Electrochemical properties of multi-walled carbon-carbon nanotubes in to tin disulfide as the negative electrode for lithium ion battery

Direct current arc-plasma method was used to make multi-walled carbon nanotube-confined metal Nanostructures (Sn@MWCNT) as precursors in a methane atmosphere, and then SnS_2@MWCNT nanostructures were obtained through in the reaction of sulfurization. The physical characterization results of the materials such as Raman, X-ray diffracted (XRD) as well as the transmission electron microscope (TEM) revealed that the size of multi-walled carbon Nanotubes was approximately 400nm, the surface carbon layer was well crystallized, as was the layer's thickness approximately 10 nanometers. Lithium-ion batteries that use Sn S2@MWCNT nanostructures for anodes materials exhibit a decent electrochemical performance. The initial discharge-charge Coulomb rate is 71%, and after 50 cycles the capacity remains constant at 703 mAh?g-1. The advantages of SnS_2@MWCNT's high-capacity nanostructured electrodes result from the fact that a range of active materials offer the capacity to work together, and also the catalyst for each of them differs.

Study on electrochemical performance of tin disulfide/single-walled carbon nanotube composite material used as anode material for lithium-ion battery

A new composite material of SnS2 with single-walled carbon Nanotubes (SWCNTs) was developed using the simple solvothermal method. It was found to have good electrochemical performance after being put on to negative electrode of lithium ion battery. When the current density is high of 1 A/gand after 100 cycle, it maintains a reversible specific capacity of 510 millions of mAh/g. We used the same method to synthesize one SnS2 material and conducted Electrochemical testing on it. The results demonstrate that, although the initial capability of SnS2 material is high, its cycle performance is low and goes through a rapid decline after less than 20 cycles. The exceptional quality of this material for lithium-ion batteries believed to be due to the synergy of the two constituents which are SnS2 and SWCNTs.
