Role of battery specific Graphene in lithium batteries

1. Anode materialDue to its unique two-dimensional structure, excellent electronic transmission capacity and large specific surface area, Graphene for batteries has great potential to replace graphite as a new generation of negative electrode material for lithium ion batteries. The lithium storage mechanism of Graphene is similar to other carbon materials. When charging, lithium ions are separated from the positive electrode and embedded in the carbon material layer, forming Li2C6. When discharging, lithium ions are separated and returned to the positive electrode. Due to the special two-dimensional structure of Graphene, When the lamellar spacing is greater than 0.7 nm, both sides of Graphene can store lithium ions. At the same time, due to the existence of wrinkles, Graphene can also store lithium. In theory, its capacity may be twice that of graphite, higher than 744 mAh/g.In addition, Graphene is mostly micro nano sized, much smaller than bulk graphite, which makes the diffusion p

Basic overview of high-purity graphite?

High purity graphite is widely used in various industries, so its use is definitely very extensive. In fact, this high-purity graphite mainly means that the carbon content of graphite is more than 99.99%. It is also widely used in advanced refractory materials and coatings in metallurgical industry, stabilizers for military initiating explosive devices, pencil lead in light industry, carbon brushes in electrical industry, electrodes in battery industry, catalyst additives in fertilizer industry, etc. Of course, the scale crystals of the product are complete, thin and tough, with excellent physical and chemical properties. It has good thermal conductivity, temperature resistance, self-lubrication, conductivity, thermal shock resistance, corrosion resistance, and other properties. In addition, the high-purity graphite (also known as flake high thermal conductivity carbon powder) mentioned today has high strength. Of course, in addition to this, it also has advantages such as good therma

The functions and characteristics of flake graphite

As a functional filler for coatings, flake graphite is mainly used for anti-corrosion coatings, fireproof coatings, and conductive coatings. As an anti-corrosion material, it is a rust resistant primer made of carbon black, talc powder, and oil, which has good chemical resistance and solvent corrosion resistance. If chemical pigments such as zinc yellow are added to the formula, the rust prevention effect will be better.The manufacturer of flake graphite believes that expandable graphite is a Graphite intercalation compound made from natural graphite flakes through chemical or electrochemical treatment. Under heating conditions, the volume of expandable graphite rapidly expands (up to 300 times), suffocating the flame and producing expanding substances that can isolate the flame, delay or interrupt its spread, be non combustible, have good flexibility, high surface energy, and good carbonization layer strength. However, the volume and dosage of the expansion body should be appropriate

How to Use Expanded Graphite

1. Protective purposesExpanded graphite can be used as a protective material to protect metals and other easily damaged objects, such as circuit boards and steel. Due to the fact that expanded graphite can expand up to 10 times, it can effectively block flames and prevent these objects from being burned by flames.2. Insulation purposeExpanded graphite can also be used as insulation material because it has good thermal resistance performance and can effectively block heat, so it can be used for insulation, such as electronic products. It can also be used for cooling, preventing heat loss, and thus providing insulation.3. Filtering purposeExpanded graphite can also be used as a filter material because it has adsorption properties and can be used to adsorb toxic substances, such as pollutants in water treatment, effectively removing pollutants from water. It can also be used for air purification to block the entry of harmful substances.4. Reinforcement purposeExpanded graphite can also b

What are the nature of ultra -fine graphite?

Ultra -fine graphite powder is one of the categories of graphite powder. The raw material of ultra -fine graphite powder is natural scales graphite. The airflow crusher or ultra -fine pieces is used to crush the natural scales graphite. The particle size of ultra -fine graphite powder reaches 6 ~ 10 μm, which is the ultra -fine graphite powder.The preparation process of ultra -fine graphite powder is: natural scales graphite and raw materials focus from compressed air to enter the crushed room by adding feed sprayer, sprayed in the crushing room, spray ultra -high -speed airflow at the crushed room , Fricate into microfimm, with a microfimm airflow, discharge from the exit tube into the hierarchical room, separate the thicker particles, and crushed it again by the rebate tube. Ultra -fine graphite powder was produced.Ultra -fine graphite powder can be widely used in the fields of conductive materials, wear -resistant lubricating materials, atomic energy industry and national defense i
