What is Tin disulfide?
Tin disulfide can be described as an inorganic compound with the chemical formula SnS2. It is an orange hexagonal flake with a CdI2 crystal structure. It isn't very soluble water, however, it is solubilized in aqua regia or hot alkaline solution, and can be found in sodium sulfide Solution, commonly used for golden paint.
Tin disulfide is soluble in hot alkali and aqua regia solution. It can undergo coordination reaction with concentrated acid, however it is unsoluble when dilute in hydrochloric acid but insoluble in water and the acid nitric. It is also able to react with ammonium sulfur to dissolve.
How do I prepare the tin disulfide?
Tin disulfide could be produced via direct fusion of tin and sulfur in the presence of the iodine. The reaction involves the heating process:
2. S -- SnS2
Another approach is to inject hydrogen sulfide through the tin (IV) salts or in the tin (IV) salt solution and cause it to precipitate.
Electrochemical behavior of multi-walled carbon-carbon nanotubes in to tin disulfide, the negative electrode of lithium ion battery
The direct current arc-plasma method was employed to produce multi-walled carbon nanotube-confined metal tin Nanostructures (Sn@MWCNT) as precursors in a methane atmosphere. Later, SnS_2@MWCNT-like nanostructures were fabricated by the sulfurization reaction. The results of the physical characterisation of the material like Raman, X-ray diffraction (XRD), and Transmission electron Microscopy (TEM) showed that the size of multi-walled carbon Nanotubes was approximately 400nm, the Carbon layer on the surface had been crystallized, in addition, the thickness of this carbon-based layer was 10 nm. Lithium-ion-based batteries using Sn S2@MWCNT nanostructures as anode materials exhibit a decent electrochemical performance. The first charge discharge Coulomb effectiveness is 71%, in the course of 50 cycle, the capacity remains stable at 703 mAh?g-1. The superior capacity characteristics of SnS_2@MWCNT nanostructured electrodes are due to the fact that a range of active material provide the capacity of the two together. The reactant platform of each is distinct.
Study on electrochemical performance of tin disulfide/single-walled carbon nanotube composite material used as anode material for lithium-ion battery
A novel composite material comprising SnS2 along with carbon nanotubes that are single-walled (SWCNTs) was created using a simple solvothermal method. It was found to have good electrochemical performance after being placed on the electrode that is negative of lithium Ion batteries. At a high current density of 1 A/g, after one hundred times it has a reversible capacity of 515 milliamps/g. To compare, we employed the same technique to make one SnS2 material, and conduct experiments on its electrochemistry. The results indicate that even though the initial specific power of SnS2 material is relatively large, the performance of its cycles is low, and diminishes quickly after less than 20 cycles. The exceptional performance of this composite material in lithium-ion batteries is thought to be the result of the synergy between two substances which are SnS2 along with SWCNTs.
