Industrialization process of battery specific Graphene lithium battery

1. Cost issuesThe cost of using Graphene as a conductive agent is much higher than that of ordinary carbon black. The cost of lithium battery is the key control factor. Without reducing the cost of raw materials, even if the electrical performance of Graphene is no better, battery manufacturers can not afford to consume hundreds of thousands of dollars per ton.2. Process issuesThe technical problems caused by the sheet structure of Graphene for batteries are mainly the preparation of electrode paste. The electrode paste requires good fluidity, dispersibility and proper viscosity. The dispersion of Graphene sheets in the electrode paste is a problem, especially the electrode paste cannot be dispersed by adding dispersants. Graphene has a large surface area, which has a great impact on the stability of the slurry settlement, cannot guarantee the consistency of each batch, and affects the battery performance.3. Other factorsThe lamellar structure of Graphene for batteries inhibits the di

Introduction to the characteristics of flake graphite

1. As a basic raw material, flake graphite can be processed into ultrafine graphite powder, expanded graphite, nano graphite powder, high-purity graphite powder, etc.2. Flake graphite has good lubricity, high temperature resistance, conductivity, etc. Processed into solid graphite lubricant, widely used in mechanical lubrication.3. The quality of flake graphite depends on its carbon content. By purifying flake graphite, it can be processed into high carbon, medium carbon, and low carbon flake graphite. Each type of graphite has a different carbon content, and the higher the carbon content, the better its industrial use.Flake graphite has strong thermal shock resistance and good corrosion resistance, making it the main carbon material for carbon refractory materials. It has important factors affecting the corrosion resistance and high-temperature working strength of carbon refractory design materials such as magnesia carbon bricks. In the actual production process, carbon refractory ma

Isostatic pressing graphite

Isostatic pressing graphite is a new product developed internationally in the past 50 years, closely linked to today's high-tech industry. It is an irreplaceable material for manufacturing single crystal furnaces, metal continuous casting graphite crystallizers, graphite electrodes for electrical discharge machining, and is also an excellent material for manufacturing rocket nozzles, graphite reactors, deceleration materials, and reflection materials. Its structure is fine and dense, the roasting process requires a particularly slow speed, and the temperature inside the furnace needs to be very uniform. This process takes about 1-2 months. The preparation process of isostatic pressing graphite includes filling the raw material powder into the mold, compacting the powder through high-frequency electromagnetic vibration, sealing and vacuuming, discharging the air between the powder particles, placing it in a high-pressure container containing liquid medium for pressure pressing, and fin

Application of graphite cathode carbon block

Carbon blocks made from high-quality anthracite, coke, graphite, etc. Used as a cathode for aluminum electrolysis cells. It is built at the bottom of the electrolytic cell, also known as the bottom carbon block. The characteristic cathode carbon block plays a dual role in conducting electricity and forming the inner lining of the electrolytic cell. Aluminum electrolysis production requires cathode carbon blocks to have high temperature resistance.

Graphite lithium battery negative electrode material

From the lead core of a pencil to the nozzle of a solid fuel rocket; Although the dark and unremarkable mass, this material composed solely of carbon atoms has quietly entered various fields of industrial production and become an indispensable part of people's lives, which is graphite. If you learned that it is still one of the core raw materials for lithium batteries and is at the forefront of the new energy electric vehicle industry today, would you feel that the investment prospects of a graphite processing enterprise are different?Graphite has good electrical conductivity and is often used to make negative electrodes for lithium batteries. Whether it is flake graphite concentrate that can be used as a solid lubricant, or spherical graphite that can more effectively encapsulate particles due to its rounded shape, it is one of the core raw materials for lithium-ion batteries.

How does pungeable graphite produce?

Because graphite is a non -polar material, it is difficult to use the small polar organic or inorganic acid intercourse alone, so oxidant is usually used. The chemical oxidation method is generally soaked in the solution of the natural scales in the solution of the oxidant and plug -in agent. Under the action of a strong oxidant, graphite is oxidized, making the macromolecular molecule of the graphite layer into a plane macromolecular with a positive charge. Due to the extrusion effect of the iconic charging between the plane macromolecules with a positive charge, the spacing between the graphite layer increases, and the plug -in agent is inserted between the graphite layer and becomes a graphite. When heating at high temperature, puffed graphite will quickly shrink, and the contraction multiple is as high as tens to hundreds or even thousands of times. The apparent volume of shrinking graphite reaches 250-300 ml/gram or more. The contracted graphite is worm -like, with a size of 0.1
