What is Tin disulfide?

/ / no Comments

What is Tin disulfide and how does it work? The inorganic compound Tin desulfide has a chemical composition of SnS2. 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 containing Tin Disulfide as Negative Electrode of Lithium Ion Battery
Multi-walled carbon-nanotube-confined metal-tin nanostructures were prepared using the direct current arc Plasma method. Brad@ihpa.net was then used as a precursor in methane, and finally brad@ihpa.net was obtained by the sulfurization process. Raman, Xray diffraction, and transmission electron microscopy were used to characterize the material. The length of the multi-walled, carbon nanotubes measured approximately 400nm. The surface carbon layer was well crystallized and the carbon layer thickness was around 10 nm. 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 different reactions platforms.
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). It has good electrochemical properties after being applied to the battery's negative electrode. 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. The SnS2 materials have a relatively high specific capacity but a poor cycle performance and decays rapidly after only 20 cycles. This composite material is superior in lithium-ion batteries because of its synergy with SnS2 (and SWCNTs).

Lithium Carbide

/ / no Comments

Lithium carbide is a lithium rich chemical compound that is a potential cathode material for lithium ion batteries. The lithium carbide consists of a lithium atom bonding to a carbon triple bond.

There are two types of lithium carbide. One is an acetylide, which is formed by reacting lithium with acetylene. Another type is a carbonate, which is formed by reacting lithium with carbon.

Lithium carbide is a solid, non-flammable compound. It is also reactive and can be used as a cathode material in a lithium ion battery.

Lithium carbide has a P6/mmm phase. This is the same symmetry as the graphite intercalation compounds found in the lithium ion rechargeable battery art.

The chemical structure of lithium carbide is not well understood. However, it has been investigated using ab initio density functional theory (DFT) crystal structure searches. In these experiments, ground state lithium carbide crystal structures were searched for at 0 GPa and 40 GPa.

Stable crystal structures were identified in the lithium-carbon binary system. These structures suggest pathways to the development of novel car-bon materials.

Theoretical studies have shown that lithium-carbon binary systems possess a wide variety of chemical compounds. Although the exact nature of these compounds has yet to be fully understood, several types of thermodynamically stable phases have been identified. These include dimers, sheets, and nanoribbons.

Thermodynamically stable lithium-carbon binary systems also exhibit a range of interesting chemical bonding characteristics. The low electronic conductivity of these molecules is believed to be the reason for the potential gap between charge and discharge.

How amazing is graphene?

/ / no Comments

What's graphene Graphene can be described as a new material that is composed of a single layer made of carbon atoms, which are packed tightly together to form a hexagonal honeycomb network. Graphene is an allotrope of carbon and a two-dimensional material.



Graphene only has 0.142 nanometers molecular bond length and 0.335 micrometers crystal plane spacing. It has four atoms of size, making it much smaller than a bacteria.
Graphene has been the thinnest known compound. It is one atom in thickness. It is also one atom thick.

Humans and graphene
Since 1948, graphene was found in nature. But it was difficult to separate graphene form the monolayer structure at the time. The graphene was all clumped together. It was almost graphite. Every millimeter contained three million layers.
Graphene, therefore, was considered non-existent for a very long time.
Scientists Konstantin Voselov (University of Manchester) discovered how to isolate graphene in 2004. The scientists discovered that graphite sheets made from highly-oriented, pyrolytic graphite could be easily separated by attaching them to special tape and then tearing it apart.
This can be repeated over and over, resulting in thinner sheets. Eventually, graphene is a special type of carbon atoms. Andrei Geim, Konstantin Novoselov received the Nobel Prize for Graphene Discovery.

Graphene The king material --
When graphene became known, it changed the face of scientific research all over the globe. One gram graphene will cover the area of a standard football field, as it is the thinnest known material.
Graphene is also very good at electrical and thermal properties. Pure monolayer graphene, which is defect-free, has a high thermal conductivity at 5300W/Mk, the highest known carbon material.
Graphene is also very good at conducting electricity. Graphene, which has a carrier mobility value of 15,000m2/(Vs at room temperatures), is 10 times more than silicon, the most widely used material.
The arrangement of carbon atoms inside graphene is like barbed wire. This arrangement of atoms gives graphene unique flexibility. It is also more difficult than ever. The graphene's unique flexibility is due to the honeycomb and barbed wire structures created by carbon atoms. Each carbon atom is also perpendicular the orbital, which allows for large bonds to penetrate atoms.

Graphene applications
The discovery graphene has opened scientists' eyes to the possibility of movement and action of particles. It has also changed many aspects of our lives.

These new energy batteries represent the first steps towards graphene tech. The lithium battery is currently the most common type of battery. While the lithium battery has the capacity to store a lot of electric power for us, the downside of the battery is its inability to last long. Each discharge or charging will reduce the battery's life expectancy.
The graphene material can greatly increase the charging efficiency and capacity of batteries. Additionally, it plays a significant role in prolonging battery life. A graphene tinoxid layer will be used as the anode for a lithium-ion battery. The battery will last longer once it is charged.
Graphene is a good choice for batteries that last longer and have a higher capacity.




Because graphene has soft properties, it could be used to create flexible material. The flexible display is one of the most iconic examples.
The flexible transparent displays produced by the South Korean Institute were made using layers of graphene, fiberglass polyester sheets and other materials. While the project is still in the development phase and has not yet been launched on the market, the project staff believes that flexible transparent displays made of graphene could one day replace "bricks", mobile phones. The phones can be folded up like silly putty.

Graphene is also used to protect our environment, most notably in desalination.
Water reacts with graphene to create a channel that is just 0.9 nanometers wide. Molecules smaller in size can pass through the channel without difficulty, but larger molecules will get stuck. Graphene can remove large molecules of salt from seawater.

Graphene's unique properties and excellent properties have led to many achievements in many scientific fields.

The Naming Method of Graphene

/ / no Comments

Graphene Graphene a material where carbon atoms are tightly packed into a single layer, two-dimensional honeycomb lattice. Graphene exhibits excellent optical, mechanical, and electrical properties. This material has great potential for applications in materials science and micro-nano processes, energy, biomedicine and drug delivery. It is expected to be a breakthrough material in the near future.
To regulate the growth of the graphene industry, it is important to have a better understanding of the concept graphene. China Graphene Standards Committee looked at single-layer and double-layers of graphene as well as single-layer and single-layer oxide graphene. There are many concepts like reduced graphene dioxide, functionalized graphene and graphene material.

The material's electronic energy band structure has exceeded its three-dimensional limit, when 10 graphene layers are present. Therefore, the standard defines graphene as being within 10 layers. A single-layer graphene is a two-dimensional material made of carbon atoms that are arranged closely in a hexagonal honeycomb structure.

Two-layer graphenereferss to two layers carbon atoms that are frequently and closely packed into a benzene ring structural (that's, a hexagonal honeycomb construction) and are made up of various stacking methods (including AB, AA, and AA' stacking). Dimensional carbon materials.

The few-layer grapheneis a 2-dimensional carbon that is composed of 3-10 layers each of carbon atoms. It can be stacked in many different ways, including ABC stacking or ABA stacking. Material.

Single-layer Grapheneoxide - A two-dimensional carbon material that has oxygen-containing functional chains attached to the surface or boundary of a one-layer graphene. Grapheneoxide is a carbon material that has oxygen-containing functional links attached to the surface and boundary at least one graphene carbon atom layer. Graphene oxide also includes the previously mentioned single-layer graphene oxygen.

Single layer reduced graphene oxygen refers to two-dimensional carbon materials obtained by deoxidizing single-layer graphene dioxide by incomplete removal (groups), of oxygen-containing functional units (groups). This can be done by heat, chemical, or electrochemical treatment.

A two-dimensional carbon substance called reduced graphene oxide is created by deoxidizing or reducing the oxygen-containing functional group (groups) of graphene oxide using chemical, electrochemical or heat treatment. One-layer reduced grapheneoxide is included in the reduction of graphene.

Functionalized graphene is a kind of graphene that contains heteroatoms/molecules (such as hydrogen, fluorine, oxygen-containing groups and other surface modification to form bonds, nitrogen, boron and other elements substitution doping, heteroatom/molecule intercalation) Etc.) Two-dimensional carbon material. Functionalized graphene can be either the grapheneoxid described above or reduced grapheneoxid.

This definition includes single-layer graphene as well as double-layer and few-layer versions of graphene. Both can be called graphene material.

What is Cementite?

/ / no Comments

Cementite and Iron Carbid are compounds of iron, carbon, or, more precisely, an intermediate metal carbide having the molecular structure Fe3C. It weighs 6.67% and 9.3% respectively. It is a gray-white crystal powder, with a relative density of 7.694. It can dissolve in water or dilute acid. Do not react with dry atmosphere. Iron oxide and carbon can be formed by oxidizing in moist oxygen. It is characterized by an orthorhombic crystal form. It is hard, fragile, and often classified as ceramic. In its purest form it is an essential component of black metalurgisty.

What does Fe3C mean?
Iron carbide Fe3C is also known by the name cementite.

How does cementite form?
Primary cementite:
When the iron-carbon mixture is in equilibrium crystallization, cementite forms. The liquid of hypereutectic alloy (hypereutectic cast iron), is then cooled to below its liquidus temperature.

Eutectic cemented cementite:
Ledeburite structures have a point strip of cementite that is uniformly distributed in an austenite matrix.

The pre-eutectoid and cementite phases of
Alloys of hypoeutectoid-hypereutectoid composition are always precipitated when the temperature decreases. This is the proeutectoid stage. Because of different conditions for forming, proeutectoid morphology can be broken down into block, Widmanstatten, and reticulate.

Eutectoid cementite:
Eutectoid is the name of cementite that's found in pearlite.

Secondary cementite
When iron-carbon alloys are slow cooled, such as hypoeutectic iron cast iron, hypereutectic iron cast iron, or hypoeutectic iron cast steel), the carbon content in austenite will reach saturation. The cementite then forms along the austenite grain border with an eutectic and eutectic distribution of microstructure. The secondary cementite, which is precipitated in austenite from the iron-carbon alloy, can be called.

Tertiary cementedite:
If the equilibrium cooling rate of iron in industry is lower than the line PQ of carbon-in-iron (FeC equilibrium diagram), then the solubility and temperature in the ferrite reach saturation. Then the temperature falls again. Due to its low quantity, the tertiary cemite is precipitated from the ferrite grain boundary. It generally occurs intermittently along that boundary.


These are those which exist outside of the mechanical mixture, like pearlite (eutectoid structural) or ledeburite.

Anode Material Carbon-coated Silicon Powder

/ / no Comments

About Anode Material Carbon-coated Silicon Powder:
The coated type silicon-carbon anode material is usually carbon coated with silicon materials of different nanostructures. This kind of material provides reversible capacity with silicon as the main body, and the carbon layer is mainly used as a buffer layer to reduce the volume effect and enhance the electrical conductivity. 


The carbon coating is usually amorphous carbon. Silicon anode materials have problems such as low cycle life, large volume change, continuous generation of SEI film, and silicon carbon anode materials can effectively improve these problems, so silicon-carbon anode materials will be the focus of the development of cathode materials in the future. A complete surface coating is important to prevent silicon from contact with the electrolyte, resulting in the depletion of a thick SEI film. The design of the microstructure is also important to maintain electron contact, ion channels, and volume expansion during the cycle.

The mechanism of carbon coating is that the bulk expansion of Si is shared by graphite and amorphous coating, which avoids the pulmonization of anode material due to huge volume change and stress in the process of intercalation and dilithium. The functions of carbon coating are: (1) Constraints and buffers the volumetric expansion of the active center; (2) prevents the agglomeration of nano-active particles; (3) prevents the electrolyte from permeating to the center to maintain a stable interface and SEI (4) silicon materials contribute high specific capacity and carbon materials contribute high conductivity.

How is Anode Material Carbon-coated Silicon Powder Produced? 
The preparation processes of silicon-carbon anode material include ball milling, high-temperature cracking, chemical vapor precipitation, sputtering deposition and evaporation. Therefore, a variety of silicon-carbon material structures are made, but they are all designed in line with the idea of increasing the capacity of lithium batteries and reducing the disadvantages of silicon particle expansion and crushing.
 
Applications of Anode Material Carbon-coated Silicon Powder:
Carbon coated silicon powder is used in cylindrical batteries, flexible packaging batteries and aluminum shell batteries.
As a new type of anode material for lithium-ion batteries, silicon carbon anode can play a more significant role in improving the energy density of batteries than the current graphite anode. However, due to its high barriers in the application, it is still in the early stage of industrialization. At present, the application prospect of silicon-carbon anode material is getting brighter and brighter.
