What's Tin disulfide?
Tin disulfide can be described as an inorganic compound that has a chemical formula of SnS2. It is a yellow hexagonal flake , with it's CdI2 Crystal structure. It is not soluble in the water, but it's liquid in aqua regia and hot alkaline solution. It's also in sodium sulfide Solution, commonly used for gold paint.
Tin disulfide soluble in the hot alkali solution. It can undergo coordination reactions with concentrated hydrochloric acid. It is non-soluble in dilute acid and insoluble in water and Nitric acid. It can also react with ammonium Sulfide to dissolve.
How do I prepare the tin disulfide?
Tin disulfide can easily be obtained by combining directly tin with sulfur in the presence of Iodine. The reaction requires heating:
2. S -- SnS2
Another option is to pour hydrogen sulfide in the solution of either tin (IV) salt solution or the tin (IV) salt solution, and then melt it.
Electrochemical properties of multi-walled carbon nanotubes that are confined with tin disulfide used as the negative electrodes of lithium ion battery
The direct current arc-plasma method was used to create multi-walled carbon-carbon nanotube-confined metal nanostructures (Sn@MWCNT) as an initial precursor in a methane environment, and later SnS_2@MWCNT nanstructures were formed by in the reaction of sulfurization. The results of the physical characterisation of the materials, such as Raman, X-ray diffraction (XRD) and transmission electron microscopy (TEM) revealed that the length of multi-walled carbon nanotubes was around 400nm. The surface carbon layer was crystallized, as was the layer's thickness about 10 nanometers. Lithium-ion batteries that use Sn S2@MWCNT nanostructures as anode materials have fairly good electrochemical performance. The initial charge-discharge Coulomb performance is 71%, After 50 cycles, it remains constant at 703 mAh?g-1. The impressive capacity of SnS_2@MWCNT nanostructured electrodes come from the fact that various types of active substances provide the capacity in combination, and the chemical reaction platform for each one is different.
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 and single-walled carbon nanotubes (SWCNTs) is prepared using an easy method of solvothermal. It is found to have an excellent electrochemical performance when placed on the electrode that is negative material of lithium ion battery. At a very high current density of 1 A/g 100 cycle, it still maintains a variable specific capacity of 510 amps/g. For comparison, we utilized this same method to create one SnS2 material and then conduct experiments on its electrochemistry. The results indicate that even though the initial specific ability of SnS2 material is quite good, its cycle performance is not as good, and it fades quickly after fewer than 20 cycles. The exceptional capability of this hybrid material within lithium-ion batteries believed to be the result of the synergy of the two elements which are SnS2 in addition to SWCNTs.
