What exactly is Tin disulfide?
Tin disulfide (also known as Tin) is an inorganic compound with chemical formula SnS2. It is an orange hexagonal flake with the CdI2 Crystal structure. It isn't very soluble the water but is soluble in aqua regia , and hot alkaline solution. It's can be found in sodium sulfide Solution, which is frequently used as golden paint.
Tin disulfide can be found in the hot alkali solution. It undergoes coordination reactions with concentrated hydrochloric acid. It is insoluble in dilute hydrochloric acid and insoluble when mixed with water and nitric acid. It can also react with ammonium Sulfide to dissolve.
How do I make the tin disulfide?
Tin disulfide is made simply by combining tin directly with sulfur in the presence of iodine. The reaction requires heat:
2. S -- SnS2
Another method is to put hydrogen sulfide into the solution of either tin (IV) salt or (IV) salt solution, and then melt it.
Electrochemical behavior of multi-walled carbon-carbon nanotubes in using tin disulfide to form the negative electrode for lithium ion battery
Direct current arc plasma technique was used to create multi-walled carbon nitrotube-confined metallic tin Nanostructures (Sn@MWCNT) as an intermediate in a methane-like atmosphere. SnS_2@MWCNT was obtained by the process of sulfurization. The results of the physical characterization of the material using Raman, Xray diffraction (XRD), and Transmission electron Microscopy (TEM) confirmed that the length of the multi-walled carbon nanotubes measured around 400nm. Furthermore, the top layer of carbon was crystallized with the thickness of carbon being approximately 10 nanometers. Lithium-ion batteries that use Sn S2@MWCNT nanostructures for anodes materials have a relatively high electrochemical performance. The first charges-discharge Coulomb efficiency is 71%, with 50 cycles of use, the capacity is still at 703 mAh?g-1. The superior capacity characteristics of SnS_2@MWCNT nanostructured electrodes result from the fact that a variety of active substances provide the capacity to work together, and also 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 novel composite material made of SnS2 with single-walled carbon Nanotubes (SWCNTs) was made by an easy method of solvothermal. It was found to have 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 times, the battery keeps a reversible reversible particular capacity of the 510 milliamps per gram. To illustrate, we applied the same technique to make a single SnS2 material and then conduct the electrochemical test on it. The results indicate that even though the initial performance of SnS2 material is relatively high, the efficiency of the cycle is poorand goes through a rapid decline after less than 20 cycles. The higher performances of this compound in lithium-ion batteries are thought to be the result of its synergy with the two components from SnS2 and SWCNTs.
