What is Tin disulfide

What's Tin disulfide?

Tin disulfide is an inorganic compound that has chemical formula SnS2. It is an orange hexagonal flake with it's CdI2 crystal shape. It's not so soluble with water, but it is soluble in aqua regia , and hot alkaline solutions. It is it is also soluble within sodium sulfide Solution, which is commonly used as gold paint.

Tin disulfide is soluble hot alkali and aqua regia solution. It may undergo coordination reaction with concentrated hydrochloric acid, however it is impermeable to dilute acids and insoluble in water and in nitric acid. It can also react with ammonium Sulfide to dissolve.

How do I make the tin disulfide?

Tin disulfide can easily be obtained by directly mixing tin and sulfur in the presence of iodine. The reaction involves heating:

2. S --- SnS2

Another method is to put hydrogen sulfide in solution of tin (IV) salt solution or the tin (IV) salt solution and cause it to precipitate.

Electrochemical properties of multi-walled carbon Nanotubes, confined using tin disulfide to form the negative electrode for lithium ion battery

Direct current arc plasma method has been used to make multi-walled carbon nanotube-confined metal Nanostructures (Sn@MWCNT) as an intermediate in a methane atmosphere, and then SnS_2@MWCNT structures were made through using the sulfurization procedure. The results of the physical characterisation of the material such as Raman, X-ray diffraction (XRD) as well as Transmission electron Microscopy (TEM) confirmed that the length of the multi-walled carbon nanotubes measured around 400nm. Furthermore, the Carbon layer on the surface had been crystallized and the thickness of the carbon layer was 10 nm. Lithium-ion batteries that use Sn S2@MWCNT nanostructures for anodes materials have an impressive electrochemical performance. The initial charge-discharge Coulomb effectiveness is 71%, following 50 cycles, this capacity still maintains 703 mAh?g-1. The high-capacity characteristics of SnS_2@MWCNT nanostructured electrodes come from the fact that many of active materials provide the capacity together, and the reactant platform of each 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 in combination with carbon nanotubes single-walled (SWCNTs) was prepared by an easy solvothermal technique. It is found to have good electrochemical performance after being used as the negative electrode of the lithium ion battery. When the current density is high of 1 A/g after hundred cycles it keeps a reversible reversible particular capacity of 515 amps/g. In order to compare, we applied the same process to synthesize one SnS2 material and then conduct experiments on its electrochemistry. The results indicate that even though the initial specific capabilities of SnS2 material is rather high, its cycle performance is not as good, and it fades quickly after fewer than 20 cycles. The better effectiveness of this alloy material when used in lithium-ion batteries believed to be the result of the synergy of the two ingredients of SnS2 along with SWCNTs.
