Tungsten Disulfide WS2 as Battery Material

The introduction of sodium batteries is expected help alleviate current limitations of lithium resource scarcity on rapid development of new energy industry.
The HTML0-ion lithium-ion battery is an essential raw material for the development of energy devices and achieving the goal to be carbon neutral. However, it’s difficult at the moment to make the capital investments in the raw material ends to meet rapidly increasing energy demand. Additionally, there is a clear structural imbalance in investment in the lithium electric sector chain which leads to rising prices for lithium raw materials.

sodium cells entered the field of vision. As an energy material, sodium is abundant in nature. It also has high capacity and high rate performance which can compensate for the limitations of lithium-ion cells in the current energy storage area. Despite the fact that sodium battery is more expensive than lithium battery because of its smaller supply chain, sodium battery with mature technology will still be an effective replacement for lithium battery. In fact, it can even be used to develop new energy fields with lithium battery.



Tungsten Disulfide will also benefit from increased market replenishment as a potential material for batteries.
Tungsten dioxide is a layered metal with remarkable surface effect, electron fluidity. The material also has high thermochemical stability and high electron densities. It is often used in sodium and lithium storage. As an example, nanocomposites that are used as conductive additions or graphene-composite as anode materials for batteries can have a higher specific capacity and discharge rate than single components WS2 or C.

Graphene, a novel anode material, has been a focus of energy storage researchers for many years. It is a versatile anode material with many benefits such as high electrical and thermal conductivity and large specific surface areas. Although it is an energy storage medium, it does not compensate for its own flaws. For example, the material is susceptible to structural collapse during a long cycle which could lead to a substantial decrease in battery power. Graphene, WS2 and other nanomaterials can be used to compensate for the graphene’s weaknesses.
The best choice for batteries materials is generally tungsten disulfide.

What Is The Applications Of Molybdenum Disulfide?

What is molybdenum sulfide?

Molybdenum disulfide This is the main component in molybdenite. It is a solid black powder with metallic luster. Molybdenum dioxide has a chemical formula: MoS2. Its melting point at 2375°C is MoS2, and its density at 4.80g/cm3 is 14°C. The Mohs hardness ranges between 1.0 and 1.5. It begins to dissolve at 1370 degC and is broken down into metallic molybdenum at 1600 degC.
Molybdenum disulfide can not be dissolved in water, dilute or concentrated sulfuric, and is usually insoluble in alkalis, organic solvents, and acids. However, it is soluble in aqua regia, boiled concentrated sulfuric, and in other acids.

What are molybdenum disulfide’s applications?

Molybdenum disulfide can be found in many carbon brush additives used in the automotive and machinery industries. You can add it to grease, grease, PTFE and nylon to increase lubrication and decrease friction.

Molybdenum dioxide can also be used for non-ferrous metals release agents and as a lubricant to forging dies. This will help extend the service life, improve working conditions, improve the running state, prevent damage from the surface, and prevent cold welding. Make sure that the threaded connection is in its best condition when connecting.

Mixing molybdenum diulfide and other volatile solvents allows it to be sprayed onto metal surfaces. It can also be added with engineering plastics for lubricating elements. Molybdenum sulfide can also be used directly in electronics, spraying or electroplating as well as hardware and screws.

Molybdenum disulfide can be used as a solid lubricant. It is particularly well-suited to high temperatures and high pressure. It is diamagnetic, so it can be used to produce a line photoconductor or a semiconductor of P-type and N-type conductivity. Additionally, it has the functions rectification as well as energy conversion. Molybdenum dioxide can be used to catalyze the dehydrogenation complex hydrocarbons.

Molybdenum disulfide, also known as “the king among advanced solid lubricants”, is another name for it. This solid powder is made of natural molybdenum powder after chemical purification. Molybdenum disulfide’s color is black, slightly silver-gray and has metallic luster. It has a greasy texture and is insoluble with water. It has good dispersibility and low adhesion. It can be added with other greases to form a colloidal condition that doesn’t adhere to them. This can increase the lubricity as well as the extreme pressure of grease.

Molybdenum disulfide works well in extreme conditions, such as high temperature, pressure, high speed, and high loads. It also prolongs equipment’s lifespan.

Molybdenum dioxidide is used in friction material to reduce friction at low temperature. It also increases friction at high temperatures.

What is Tin disulfide?

What is Tin disulfide ? Tin desulfide A chemical formula of SnS2 is an inorganic compound. It is a yellow hexagonal flake containing a CdI2 crystalline structure. It is very insoluble in water. However, it is easily soluble and soluble with aqua regia, hot alkaline solution, as well as sodium sulfide solution. This is often used to make golden paint.
Tin disulfide dissolves in hot alkali solution or aqua regia. It can also react with ammonium-sulfide to disperse.
How to prepare Tin Disulfide
Tin disulfide is made by mixing tin and sulfur with iodine. This reaction needs heating.
Sn + 2 SnS2
Another option is to pass hydrogen sulfuride into the Tin (IV) salt, or Tin (IV), salt solution and precipitate.
Electrochemical behaviour of multi-walled Carbon Nanotubes confined Tin disulfide used as a Negative Electrode of Lithium Ion Battery
Multi-walled carbon-confined metal-tin nanostructures were prepared using the direct current arc Plasma method. Brad@ihpa.net was first prepared by heating a methane atmosphere with a precursor. Then, brad@ihpa.net was made through the sulfurization process. Raman, XRD (XRD) as well as transmission electron microscopy, (TEM) revealed that the multi-walled carbon-nanotubes were about 400nm in length, that the surface carbon layer was well crystallized and that the carbon layer was approximately 10 nm thick. Sn brad@ihpa.net Nanostructures are used as anode material in lithium-ion battery. They show a good electrochemical performance. The first charge-discharge Coulomb efficiency of 71% is achieved, and after 50 cycles the capacity maintains 703?mAh?g-1. Brad@ihpa.net Nanostructured Electrodes have high-capacity properties due to the fact that different active materials provide the capacity together and that each material’s reaction platform is unique.
Study on electrochemical performance of tin disulfide/single-walled carbon nanotube composite material used as anode material for lithium-ion battery
The simple solvothermal process allowed for the creation of a new composite material consisting of SnS2 (SWCNTs), and single-walled, carbon nanotubes (SWCNTs). After it is applied to the lithium-ion battery’s negatively electrode material, it has excellent electrochemical performance. It maintains a specific capacity of 515 mAh/g even at high current density (1 A/g), after 100 cycles. To compare, we used the exact same method to synthesize one SnS2 materials and performed electrochemical tests. Although the SnS2 materials have a relatively high initial specific capability, they are slow to degrade and decay quickly after only 20 cycles. The synergy between SnS2 & SWCNTs is thought to explain the superior performance of this composite material for lithium-ion batteries.

Molybdenum Disulfide MoS2 Powder CAS 1317-33-5

About Molybdenum Disulfide MoS2 Powder:
Molybdenum disulfide (MoS2) is the main component of molybdenite. Black solid powder with a metallic luster. Chemical formula MoS2, melting point 1185°C, density 4.80g/cm3 (14°C), Mohs hardness 1.01.5. It starts to decompose at 1370°C and decomposes into metallic molybdenum and sulfur at 1600°C. It starts to be oxidized when heated at 315°C in the air, and the temperature rises and the oxidation reaction accelerates. Molybdenum disulfide is insoluble in water, dilute acid and concentrated sulfuric acid. It is generally insoluble in other acids, alkalis and organic solvents, but it is soluble in aqua regia and boiling concentrated sulfuric acid. Slowly oxidized at 400 ℃ to generate molybdenum trioxide:
2MoS2+ 7 O2→ 2 MoO3 + 4 SO2 can be used to test the generated molybdenum trioxide with ferrotitanium reagent. First, the product is treated with sodium hydroxide or potassium hydroxide solution (the principle is to convert molybdenum trioxide into molybdate), and then the titanium iron reagent solution is added dropwise, which will react with the generated sodium molybdate or potassium molybdate to produce gold Yellow solution. This method is very sensitive, and trace amounts of molybdate can be detected. And if there is no molybdenum trioxide generated, the solution will not produce golden yellow, because molybdenum disulfide does not react with sodium hydroxide or potassium hydroxide solution.
Molybdenum disulfide can react with chlorine when heated to produce molybdenum pentachloride:
2 MoS2+ 7 Cl2→ 2 MoCl5+ 2 S2Cl2
Molybdenum disulfide and alkyl lithium react under control to form an intercalation compound (interlayer compound) LixMoS2. If it reacts with butyllithium, the product is LiMoS2.
Molybdenum disulfide has a high content of active sulfur, which is easy to cause corrosion to copper. It is discussed in many books and papers on lubricant additives. In addition, when the parts made of copper and its alloys need to be lubricated, it is not impossible to use molybdenum disulfide lubricating products, but also to add copper corrosion inhibitors. Feel free to send an inquiry to get the latest price if you would like to buy Molybdenum Disulfide MoS2 Powder in bulk.

How is Molybdenum Disulfide MoS2 Powder produced?
Natural law
MoS2 can be prepared by the natural method, namely the molybdenite concentrate purification method, which is to remove the acid-insoluble matter in the molybdenite concentrate, SiO2, Fe, Cu, by subjecting high-quality molybdenum concentrate to certain physical and chemical actions. Ca, Pb and other impurities are further refined to obtain nano-MoS2. However, the purity of the nano-MoS2 produced by the natural method is not high, and the purification technology needs to be further improved. When the temperature is lower than 400℃, it is recommended to use the most expensive MoS2 when working in ordinary atmosphere. It has lubricating ability below 1300℃, and it is recommended to use the cost-based MoS2.
Chemical synthesis
The synthetic method can produce sulfides with high purity, less impurities, and fine particle size, and can prepare sulfides that meet different functional requirements. Therefore, the production of nano sulfides by synthetic methods has always attracted much attention. There are many methods for preparing nano-MoS2, such as ammonium tetrathiomolybdate thermal decomposition method, hydrogen sulfide or sulfur vapor reduction method, high-energy ball milling method, carbon nanotube space confinement method, hydrothermal synthesis method, high-energy physical method and chemical method combination and many more.

Applications of Molybdenum Disulfide MoS2 Powder:
Molybdenum disulfide is diamagnetic, can convert linear photoconductors and semiconductors with P-type or N-type conductivity, and has the functions of rectification and energy conversion.
Molybdenum disulfide can also be synthesized as a catalyst for hydrocarbon dehydrogenation.
Molybdenum disulfide is also known as “the king of advanced solid lubricants”.
Molybdenum disulfide is a solid powder made from natural molybdenum concentrate chemically purified by changing the molecular structure.
Molybdenum disulfide has good dispersibility and does not need to be added. It can be added to various greases to form a colloidal state and will never replace it, thereby increasing the lubricity and extreme pressure of the grease.
Molybdenum disulfide is also suitable for high temperature, high pressure, high viscosity and high load mechanical working conditions to extend the service life of the equipment.
The main function of molybdenum disulfide as a friction material is to reduce friction at low temperatures, increase friction at high temperatures, and reduce combustion loss. Easily volatilize in the friction material.
Anti-friction: The size of disulfide particles formed by supersonic jet pulverization can reach 325-2500 mesh, the particle hardness is 1-1.5, and the friction coefficient is 0.05-0.1, so it can be used in friction materials to take advantage of the anti-friction effect;
Increased friction: Molybdenum disulfide is not conductive, and silicon carbide, molybdenum disulfide, molybdenum trisulfide and molybdenum trioxide are present. When the temperature of the friction material rises sharply due to friction, the shrinking molybdenum trioxide particles gradually heat up and expand, thereby increasing the friction in the axial direction.
Antioxidant: Molybdenum disulfide is obtained through a comprehensive chemical purification reaction, and its pH value changes 7-8, slightly alkaline. It covers the surface of the friction material, which can protect other materials from oxidation, especially making it difficult for other materials to move and enhancing adhesion.

Storage Condition of Molybdenum Disulfide MoS2 Powder:
