What exactly is Tin disulfide?

Tin disulfide is a non-organic compound that has a chemical formula of SnS2. It is an yellow hexagonal flake that has the CdI2 crystal shape. It isn't soluble in water, however, it is solubilized in aqua regia or hot alkaline solution. It is it is also soluble within sodium sulfide Solution, which is commonly used as gold paint.

Tin disulfide will dissolve in aqua regia and hot acid solution. It may undergo co-reaction with concentrated acid, however it is non-soluble in dilute acid and insoluble in water and in nitric acid. It also reacts with ammonium sulfide , causing it to dissolve.

How do I make the tin disulfide?

Tin disulfide can be made by directly mixing tin and sulfur with the iodine. The reaction requires heating:

2. S -- SnS2

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

Electrochemical properties of multi-walled carbon nanotubes that are confined with tin disulfide used as the negative electrode for lithium ion battery

Direct current arc plasma method was employed to produce multi-walled carbon Nanotube-confined tin Nanostructures (Sn@MWCNT) as an initial precursor in a methane atmosphere. Later, SnS_2@MWCNT-like nanostructures were fabricated by their sulfurization reactions. The results of physical analysis of the material using Raman, Xray diffraction (XRD), and transmission electron microscopy (TEM) revealed that the length of multi-walled carbon nanotubes was approximately 400nm, the carbon layer on the surface was well crystallized, and the thickness of the carbon layer was around 10 nanometers. Lithium-ion batteries that use Sn S2@MWCNT nanostructures as anode materials exhibit a decent electrochemical performance. The first discharge-charge Coulomb effectiveness is 71%, After 50 cycles of use, the capacity remains stable at 703 mAh?g-1. The high-capacity characteristics of SnS_2@MWCNT nanostructured electrodes result from the fact that a range different active materials are able to provide capability together, and the reaction platform for each material 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 substance made of SnS2 combined with single-walled carbon nanotubes (SWCNTs) was produced using a simple solvothermal method. It was found to have excellent electrochemical characteristics after being connected to the negative electrode material of the lithium ion battery. When the current density is high at 1 A/g, and after 100 times, the battery has a reversible specific power of more than 510 millions of mAh/g. For comparison, we utilized the same process to synthesize a single SnS2 material and then conduct experiments on its electrochemistry. The results show that even though the initial specific capacity of the SnS2 material is quite good, its cycle performance is low, and will begin to decline after only 20 cycles. The superior capability of this hybrid material within lithium-ion batteries believed to be due to it being a synergy between both component of SnS2 in addition to SWCNTs.
