What exactly is Tin disulfide?
Tin disulfide is an organic compound that has the chemical formula SnS2. It is a yellow hexagonal flake containing that has a CdI2 crystal form. It's not so soluble with the water, but it's easily soluble in aqua regia as well as hot alkaline solutions, and it is also soluble within sodium sulfide Solution, which is often used as golden paint.
Tin disulfide can be found in the alkali in hot and aqua regia solution. It can also undergo the coordination reaction in concentrated hydrochloric acid. However, it's not soluble in dilute acid that is insoluble with water and Nitric acid. It can also react with ammonium Sulfide to dissolve.
How do you make Tin disulfide?
Tin disulfide can easily be obtained by combining directly tin with sulfur in the presence of iodine. The reaction requires the heating process:
Sn + 2 S -- SnS2
Another technique is to add hydrogen sulfide in the solution of either tin (IV) salt or tin (IV) salt solution to melt it.
Electrochemical behavior of multi-walled carbon nanotubes held in to tin dioxide as the negative electrodes for lithium ion battery
Direct current arc-plasma method has been used to make multi-walled carbon nitrotube-confined metallic tin Nanostructures (Sn@MWCNT) as an initial precursor in a methane atmosphere, and then SnS_2@MWCNT-like nanostructures were fabricated by the process of sulfurization. The physical characterization results of the material , such as Raman, Xray diffraction (XRD) as well as the transmission electron microscope (TEM) confirmed that the length of multi-walled carbon-carbon nanotubes was 400nm. The Carbon layer on the surface had been crystallized, as was the layer's thickness around 10 nm. Lithium-ion batteries made of Sn S2@MWCNT nanostructures as anode materials have an impressive electrochemical performance. The initial discharge-charge Coulomb efficiency is 71%, following 50 cycles, it still maintains 703 mAh?g-1. The characteristics of high-capacity SnS_2@MWCNT nanostructured electrodes result from the fact that a variety of active substances provide the capacity to work together, and also the reactions platform of each one differs.
Study on electrochemical performance of tin disulfide/single-walled carbon nanotube composite material used as anode material for lithium-ion battery
A novel composite made up of SnS2 combined with single-walled carbon nanotubes (SWCNTs) was made by an easy solvothermal technique. It has good electrochemical performance after being placed on the electrode that is negative material of lithium Ion batteries. At a high current density of 1 A/g, after 100 cycles, it has a reversible specific power of 510 milliamps/g. As a comparison, we used the same technique to make one SnS2 material and then conduct studies on electrochemistry on the material. The results show that even though the initial power of SnS2 material is relatively high, the cycle performance is low, and fades quickly after fewer than 20 cycles. The higher capacity of this particular composite for batteries that use lithium is thought to be due to the synergy between the two parts of SnS2 along with SWCNTs.
