Graphite powder is a widely used industrial material, which is obtained from high-purity graphite after crushing, grinding, and screening. The classification of graphite powder is mainly based on the particle size, ranging from 50 mesh to 30000 mesh. The larger the mesh, the finer the particle size, and the higher the price.

    Graphite powder is a form of graphite with excellent electrical and thermal conductivity, which make it an important part of modern batteries. It is dispersed in the liquid to produce a stable colloid. The liquid is usually water, but other liquids can also be used. A colloid itself is a mixture of substances finely dispersed in another substance to produce a suspension-like effect, with graphite particles suspended in a liquid medium.

    Application of colloidal graphite powder in batteries

    When the battery is charged, electrons are withdrawn from the graphite anode and stored inside the battery. When the battery is in use, this stored electrical energy is released to provide power to the devices to which it is connected.

    (1) It has become an increasingly popular choice in anode manufacturing due to its unique properties. Since graphite particles are suspended in a liquid, they are able to form a more uniform and consistent structure within the anode. This results in the overall battery system being more reliable and efficient.

    (2) It can be easily dispersed in liquid media. This allows for a greater degree of customization in terms of battery design. By adjusting the concentration of colloidal graphite powder in the liquid, manufacturers can create anodes with different properties suitable for specific applications.

    Advantages of colloidal graphite powder

    Colloidal graphite powder is produced through a process called “chemical exfoliation,” which involves the use of chemicals to break down graphite into individual layers.

    (1) It can improve the conductivity of the battery. This means that current can flow through the battery more easily and efficiently, improving battery life and performance. The powder is highly conductive and has a larger surface area than conventional graphite powder. Therefore, it is very effective in improving battery performance. Colloidal graphite powder also has a higher energy storage capacity, which makes it an ideal material for use in high-capacity batteries. As the demand for high-performance batteries continues to increase, the use of colloidal graphite powder is likely to become more common.

    (2) Improve the safety of the battery. Traditional graphite powder is prone to thermal runaway, a phenomenon in which batteries overheat and can explode. However, it has a lower tendency to this phenomenon, making it a safer material for batteries.

    (3) Tiny particles: The particle size usually does not exceed 10 microns. Due to its tiny size and high degree of purity, this material can perform at its best in electric vehicle batteries.

    (4) Chemical stability: can maintain the normal working condition of the battery for a long time. Because of this property, it is widely used in rechargeable lithium-ion batteries. By adding the right amount of colloidal graphite powder to the battery, the performance of the battery can be significantly improved.

    Preparation and use of colloidal graphite powder

    (1) Preparation: Franli factory usually uses mechanical grinding, chemical reduction and other methods, which can greatly repair the structural defects in graphite materials and improve the electrical and thermal conductivity of graphite materials. The obtained colloidal graphite powder can not only be directly added to battery materials, but also play an important role in thermal conductive materials, coatings, catalysts and other fields.

    (2) Use: It is necessary to ensure the appropriate amount of addition and appropriate material formulation. If the concentration of colloidal graphite powder is too high, it will lead to a decrease in the performance of the battery. Therefore, battery manufacturers must accurately calculate the optimal amount of addition to achieve optimal performance. In addition, the choice of colloidal graphite powder is also important, and materials with high purity should be selected to ensure stable performance and long life cycle of the battery.

    It is a key ingredient in modern batteries because of its ability to produce highly efficient anodes. As technology continues to advance and the need for better battery systems continues to grow, colloidal graphite powder is likely to continue to be an important element in battery manufacturing for many years to come.
