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.

Tungsten disulfide uses

Tungsten dioxide is an common compound of tungsten, sulfur. It is composed one tungsten atom as well as two sulfur atoms. Tungsten Disulfide Chemical Formula Is WS2. It has great thermodynamic and optoelectronic properties.
Tungsten disulfide Properties
Low friction
The dynamic coefficient (WS2) of tungsten dioxide is 0.030. While the static coefficient ranges from 0.070 – 0.090, it is between 0.070 – 0.090. The results can be affected by pressure, surface finish, and surface hardness. The results of extensive, continuous, real-life wear show little to no change in time unless extreme overload conditions are applied.

Chemistry stability
Tungsten diulfide (WS2) has a non-toxic, inert nature and is also non-corrosive. You can apply WS2 to any stable metal substrate. It does not react to most solvents. The fluorine and sulfuric acids, hydrofluoric acid, as well hot caustic solutions can cause erosion. While WS2 has a high resistance to corrosion, it is not able to prevent corrosion from inherently weak materials.

Compatibility
The WS2 can be used to make petrochemical oils, greases and synthetic oils as well as hydraulic oils. This oil has a natural affinity for lubricants. It strives to preserve the fluid power layer.

High operating temperatures
The temperature at which WS2 operates is between -460 and 1200 degF under normal conditions, or 2400 degF when operating in vacuum. The threshold for oxidation is 825°F. This is a very low level compared to other oils. It also has very low exhaust characteristics. Because of its high resistance to heat, tungsten fluoride is ideal for fitting bolts into studs or shafts in exhaust systems on all makes and models of cars.

What’s tungsten disulfide for?
Petroleum catalyst:
Due to its outstanding cracking ability, high catalytic activities, and extended service life, WS2 can also be used as catalysts for hydrogenation, desulfurizations, polymerizations, reforming and hydroxylation.

A solid lubricant
The friction coefficient for WS2 ranges from 0.01 to 0.03 and its compressive strength as high as 2100MPa. This lubricant has many advantages, including a high lubrication temperature, long life span, low friction coefficient, corrosion resistance, good temperature resistance, and good load resistance. Therefore, it is frequently used to lubricate high temperatures, high pressures, high speeds, and transport equipment using chemical active media.

As energy storage electrode material:
WS2 refers to a type layered material that is interconnected by WMurS and van der Waals forces between layers. The distance between the layers is medium. This gives it good thermochemical stability, high storage performance, fast electron transfer rates, and excellent energy density.

Chip transistors
Low-dimensional semiconductor materials made from transition metals such as WS2 can be used to make semiconductor devices capable of more data processing and storage.

A high-performance additive for lubricating oil.
It has been shown that adding the appropriate amount of WS2 Nanoparticles to the Lubricating Oil can significantly improve its lubrication performance, decrease the friction coefficient by 20%-50%, increase oil film strength and reduce friction coefficient by 20%-50%. The lubrication performance of WS2 nanoparticles is superior to that of Nano-MoS2.

How is Tungsten Carbide Powder Produced?

WC powder is produced through the direct carburization of tungsten powder. Various processes are used to produce ultra-fine WC powders. The particle size of the WC particles determines the size of the WC powder.

Traditionally, the hydrogen reduction method is used to synthesize WC. This process involves pressing or sphericalizing a mixture of WO3 and graphite, and then heating it to a high temperature. In addition to the resulting tungsten carbide, other intermediate products are formed.

Recently, nano-scale WC powders have been produced by thermal plasma reaction system. They are less than 20 nm in diameter. These WC powders can contain small amounts of W2C phase.

A solvothermal method is also used to synthesize WC powder. The original mixture is heated to a specific temperature in a sealed container with an organic or non-aqueous solvent.

Another approach is the use of a carbon black as a reductant. During the C diffusion reaction, a thin layer of WC grows around the W particles. It is this thin layer that enables the growth of polycrystalline WC.

Carbonized WC powder is analyzed by Venables and Brown. Increasing the insulation time increases the oxygen content of the WC powder. But it is crucial to control the insulation time. Higher temperatures have a significant effect on the particle size of WC.

Spherical tungsten carbide powder is mainly made from a mixture of tungsten and tungsten carbide. It is characterized by good hardness and wear resistance.

Tungsten Carbide WC Powder Cas 12070-12-1

About Tungsten Carbide WC Powder:
Tungsten carbide is a compound composed of tungsten and carbon, with a molecular formula of WC and a molecular weight of 195.85.The most basic form of tungsten carbide is a fine gray powder, but it can be pressed into shapes through a process called sintering for use in industrial machinery, cutting tools, abrasives, armor-piercing bullets, and jewelry.
 
The stiffness of tungsten carbide is about twice that of steel, and Young’s modulus is about 530-700 GPa (77,000 to 102,000 ksi), which is twice the density of steel and is almost between lead and gold. Its hardness is comparable to that of corundum (α-Al2O3), and only cubic boron nitride and diamond powder, grinding wheels and compounds with high hardness abrasives can be used for polishing and finishing.
 
Tungsten carbide is a black hexagonal crystal with metallic luster and hardness similar to that of a diamond. It is a good conductor of electricity and heat. Tungsten carbide is insoluble in water, hydrochloric acid and sulfuric acid, but easily soluble in a mixed acid of nitric acid and hydrofluoric acid. Pure tungsten carbide is fragile, and if a small amount of titanium, cobalt and other metals are added, the brittleness can be reduced. Tungsten carbide used as a steel cutting tool is often added with titanium carbide, tantalum carbide or their mixture to improve the anti-knock ability. Tungsten carbide is chemically stable. Tungsten carbide powder is used in cemented carbide production materials. Feel free to send an inquiry to get the latest price if you would like to buy Tungsten Carbide WC Powder in bulk.

How is Tungsten Carbide WC Powder produced?
Using metal tungsten and carbon as raw materials, tungsten powder with an average particle size of 3 to 5 μm and carbon black of the same amount are dry mixed with a ball mill, fully mixed, press-molded, and placed into a graphite plate, and then placed in a graphite resistance furnace Or it can be heated to 14001700℃ in an induction furnace, preferably 15501650℃. In the hydrogen stream, W2C is initially produced and continues to react at high temperatures to produce WC. Or firstly, tungsten hexacarbonyl is thermally decomposed at 650-1000°C in the CO atmosphere to obtain tungsten powder, and then reacted with carbon monoxide at 1150°C to obtain WC. Temperatures higher than this temperature can generate W2C.
Chemical reaction formula:
2W + C = W2C
W + C = WC
Tungsten trioxide WO3 is hydrogenated and reduced to prepare tungsten powder (average particle size 35μm). Then, the mixture of tungsten powder and carbon black in an equimolar ratio (dry-blended with a ball mill for about 10 hours) is press-formed under a pressure of about 1t/cm2. Put the pressurized material block into a graphite pan or crucible, and heat it to 14001700℃ (preferably 15501650) in a hydrogen stream (using pure hydrogen with a dew point of -35℃) using a graphite resistance furnace or an induction electric furnace ℃), carburizing will produce WC. The reaction starts from around the tungsten particles, because W2C is generated at the beginning of the reaction, and because the reaction is incomplete (mainly because the reaction temperature is low), unreacted W and intermediate W2C remain in addition to WC. Therefore, it must be heated to the above-mentioned high temperature. The maximum temperature should be determined according to the particle size of raw tungsten. For coarse particles with an average particle size of about 150 μm, the reaction proceeds at a high temperature of 1550 to 1650°C.
Chemical reaction formula:
WO3 + 3H2 → W + 3H2O
2WO3 + 3C → 2W + 3CO2
2W + C = W2C
W + C = WC

Applications of Tungsten Carbide WC Powder:
Tungsten carbide is widely used as high-speed cutting tools, furnace structural materials, jet engine parts, cermet materials, resistance heating elements, etc. Used to manufacture cutting tools, wear-resistant parts, melting crucibles for metals such as copper, cobalt, and bismuth, and wear-resistant semiconductor films.
Tungsten carbide is used as super-hard tool material and wear-resistant material.
Tungsten carbide can form a solid solution with many carbides. WC-TiC-Co cemented carbide tools have been widely used.
Tungsten carbide can also be used as a modified additive of NbC-C and TaC-C ternary system carbides, which can reduce the sintering temperature and maintain excellent performance. It can be used as aerospace materials.
Tungsten carbide (WC) powder can also be synthesized by using tungsten anhydride (WO3) and graphite in a reducing atmosphere at a high temperature of 14001600℃. Dense ceramic products can be obtained by hot pressing sintering or hot isostatic pressing sintering.
Tungsten carbide (WC) powder can also be used to produce high capability nano-crystalline or superfine horniness alloy, hard-face abrasion-resistant spraying and petrochemical cracking catalyst; Chipless forming tools; Cutting tools; Mining tolls; Nano-composites (for enhanced hardness, strength, and wear resistance); Erosion-resistant coatings; wear-resistance coatings; Corrosion-resistant coatings; Wear-resistant parts.
