What is Tin disulfide

What exactly is Tin disulfide?

Tin disulfide - an inorganic compound that has the chemical formula SnS2. It is a yellow hexagonal flake , with an CdI2 crystal form. It isn't really soluble in the water, but it's water-soluble in aqua regia. It is also soluble in hot alkaline solutions, and as well in sodium sulfide Solution, commonly used for gold paint.

Tin disulfide soluble in aqua regia and hot alkali solution. It may undergo the coordination reaction in concentrated hydrochloric acid. However, it is imsoluble within dilute hydrochloric acid as well as insoluble in water and nitric acid. It also reacts with ammonium sulfur to dissolve.

How do I make tin disulfide?

Tin disulfide is made by mixing directly tin and sulfur with the iodine. The reaction involves heat:

2. S --- SnS2

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

Electrochemical properties of multi-walled carbon nanotubes held in by tin disulfide. It is the negative electrode for lithium ion battery

Direct current arc-plasma method was employed to produce multi-walled carbon-carbon nanotube-confined metal Nanostructures (Sn@MWCNT) as precursors in a methane atmosphere. Then, SnS_2@MWCNT-like nanostructures were fabricated by the process of sulfurization. The results of the physical characterisation of the material , such as Raman, X-ray Diffraction (XRD) and Transmission electron Microscopy (TEM) showed that the length of multi-walled carbon-carbon nanotubes was approximately 400nm, the carbon layer that was on the surface was crystallized, while the size of the carbon layer was around 10 nanometers. Lithium-ion cells using Sn S2@MWCNT nanostructures for anodes materials have relatively good electrochemical performance. The initial charging and discharging Coulomb yield is 71% After 50 cycles, it still maintains 703 mAh?g-1. The characteristics of high-capacity SnS_2@MWCNT nanostructured electrodes result from the fact that many of active substances provide the capacity , as well as the reaction 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 new composite substance made of SnS2 with single-walled carbon Nanotubes (SWCNTs) was developed using an easy solvothermal process. It has high electrochemical efficiency after being placed on the electrode that is negative of the lithium Ion battery. At a very high current density of 1 A/g after 100 cycles retains a reversible capacity of approximately 510 mAh/g. For comparison, we utilized the same technique to make a single SnS2 material and then conduct electrochemical tests on it. The results demonstrate that, although the initial capacities of SnS2 material is quite high, the efficiency of the cycle is not great, and will begin to decline after only 20 cycles. The exceptional effectiveness of this alloy material when used in lithium-ion batteries believed to be due to the synergy between the two ingredients of SnS2 as well as SWCNTs.
