What is Tin disulfide

What exactly is Tin disulfide?

Tin disulfide - an inorganic compound that has the chemical formula SnS2. It is a yellow hexagonal flake , with an CdI2 crystal form. It isn't very soluble water, however it's soluble in aqua regia and hot alkaline solution. It is as well in sodium sulfide Solution, often used as gold paint.

Tin disulfide is soluble in aqua regia and hot acid solution. It can undergo co-reaction with concentrated acid, but it is non-soluble in dilute acid and is insoluble in water and nitric acid. It is also capable of resolving with ammonium sulfide , causing it to dissolve.

How to prepare the tin disulfide?

Tin disulfide can be made by combining directly tin with sulfur with the iodine. The reaction requires heat:

2. S --- SnS2

Another option is passing hydrogen sulfide in the solution of either tin (IV) salt and tin (IV) salt solution to create a precipitate.

Electrochemical behavior of multi-walled carbon-carbon nanotubes in by tin disulfide. It is the negative electrode for lithium ion battery

The direct current arc plasma technique was used to make multi-walled carbon nanotube-confined metal tin nanostructures (Sn@MWCNT) as an intermediate in a methane environment, and later SnS_2@MWCNT nanostructures were obtained through using the sulfurization procedure. The results of physical characterization of the material , such as Raman, X-ray Diffraction (XRD), and transmission electron microscopy (TEM) demonstrated that the length of multi-walled carbon-carbon nanotubes was around 400nm. The top layer of carbon was crystallized it was thicker than the surrounding carbon, approximately 10 nm. Lithium-ion batteries made of Sn S2@MWCNT nanostructures as anode materials exhibit a decent electrochemical performance. The initial charging and discharging Coulomb efficiency is 71% and after 50 cycles, it still remains at 703mAh?g-1. The capacity-enhancing properties of SnS_2@MWCNT nanostructured electrodes are due to the fact that different types of active substances provide the capacity , as well as the reactant platform of each is different.

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 created using an easy solvothermal procedure. It has high electrochemical efficiency after being added to the negatively electrode material of lithium Ion battery. In a high density of current of 1 A/gand after 100 cycles has a reversible capacity of 500 mg/g. To illustrate, we applied the same process to synthesize a single SnS2 material and conduct experiments on its electrochemistry. Results indicate that although the initial capabilities of SnS2 material is quite excellent, the cycle efficiency is not great, and goes through a rapid decline after less than 20 cycles. The exceptional efficiency of the composite in batteries made from lithium is believed to be due to the synergy between two substances of SnS2 along with SWCNTs.
