What's Tin disulfide?

Tin disulfide is a non-organic compound that has the chemical formula SnS2. It is a yellow hexagonal flake with the CdI2 Crystal structure. It isn't really soluble in water, however it's soluble in aqua regia and hot alkaline solutions. It is also soluble in sodium sulfide Solution, commonly used for golden paint.

Tin disulfide is insoluble in aqua regia as well as hot alkali solution. It may undergo coordination reactions when exposed to concentrated hydrochloric acid. However, it is imsoluble within dilute hydrochloric acids and insoluble when mixed with water and the acid nitric. It also reacts with ammonium sulfide and dissolve.

How do you make Tin disulfide?

Tin disulfide could be produced through the direct combination of tin with sulfur in the presence of iodine. The reaction requires heating:

Sn + 2 S --- SnS2

Another approach is to inject hydrogen sulfide in the tin (IV) salt solution or the tin (IV) salt solution and precipitate it.

Electrochemical properties of carbon nanotubes with multi-walled walls confined tin disulfide as negative electrode in lithium ion battery

Direct current arc plasma method was used to make multi-walled carbon carbon nanotube confined metal tin nanostructures (Sn@MWCNT) as an intermediate in a methane atmosphere, and then SnS_2@MWCNT nanstructures were formed by their sulfurization reactions. The results of the physical characterization of the material using Raman, Xray diffraction (XRD) and Transmission electron Microscopy (TEM) revealed that the length of multi-walled carbon-carbon nanotubes was approximately 400nm, the top layer of carbon was crystallized it was thicker than the surrounding carbon, approximately 10 nm. Lithium-ion cells using Sn S2@MWCNT nanostructures for anodes materials exhibit a decent electrochemical performance. The initial charge discharge Coulomb rate is 71%, even after 50 times, the power remains at 703 mAh?g-1. The impressive capacity of SnS_2@MWCNT nanostructured electrodes stem from the fact that several types of active materials offer the capacity to work together, and also the reaction platform of each is unique to each material.

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

A new composite substance made of SnS2 with single-walled carbon Nanotubes (SWCNTs) was produced using an easy solvothermal process. It has excellent electrochemical properties after being added to the negatively electrode of the lithium Ion batteries. With a high current density of 1 A/g, after 100 cycle, it still retains a reversible capacity of 515 milliamps/g. As a comparison, we used the same method for synthesis of one SnS2 material and conducted experiments on its electrochemistry. The results show that even though the initial specific power of SnS2 material is quite high, its cycle performance is low, and will begin to decline after only 20 cycles. The exceptional performance of this composite material in lithium-ion batteries is believed to be the result of the synergy of the two component from SnS2 as well as SWCNTs.
