What is Tin disulfide?
Tin disulfide can be described as an inorganic compound that has a chemical formula of SnS2. It is the yellow hexagonal flake which has one CdI2 crystal structure. It isn't very soluble water, but it is easily soluble in aqua regia as well as hot alkaline solution, and also soluble in sodium sulfide Solution, commonly used for gold paint.
Tin disulfide can be found in aqua regia and hot alkali solution. It undergoes coordination reactions with concentrated hydrochloric acid. It is dissolvable in dilute hydrochloric acid and insoluble when mixed with water and the acid nitric. It may also react with ammonium sulfide and dissolve.
How do I make the tin disulfide?
Tin disulfide is made by directly mixing tin and sulfur in the presence of Iodine. The reaction requires heating:
2. S -- SnS2
Another option is passing hydrogen sulfide in the solution of either tin (IV) salt , or into the tin (IV) salt solution, and then cause it to precipitate.
Electrochemical behavior of multi-walled carbon nanotubes confined to tin disulfide, the negative electrodes of lithium ion battery
The direct current arc plasma method was employed to create multi-walled carbon nanotube-confined metal tin Nanostructures (Sn@MWCNT) as the precursor under a methane-like atmosphere. SnS_2@MWCNT nanostructures were obtained through this sulfurization. The results of the physical characterization of the substance, including Raman, Xray 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 it was thicker than the surrounding carbon, about 10 nm. Lithium-ion cells using Sn S2@MWCNT nanostructures for anodes material have shown relatively good electrochemical performance. The first discharge-charge Coulomb efficacy is 71%, in the course of 50 cycle, the power remains at 703 mAh?g-1. The advantages of SnS_2@MWCNT's high-capacity nanostructured electrodes are due to the fact that many of active substances provide the capacity in combination, and the reaction platform of each material 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 novel composite material comprising SnS2 in combination with carbon nanotubes single-walled (SWCNTs) was created using an easy solvothermal process. It is found to have excellent electrochemical characteristics after being applied to the negative electrode material of the lithium Ion batteries. At a current density of 1 A/g 100 cycles still retains a reversible capacity of approximately 510 mAh/g. For comparison, we used the same method to synthesize one SnS2 material and then conduct studies on electrochemistry on the material. The results reveal that while the initial specific capacity of the SnS2 material is quite large, the performance of its cycles is low and diminishes quickly after less than 20 cycles. The exceptional quality of this material for lithium-ion batteries thought to be the result of an interaction between the two constituents which are SnS2 as well as SWCNTs.
