Spherical graphite is a raw material with high-quality high-carbon natural scaly graphite

Overview of Spherical Graphite Powder

Spherical graphite is a raw material with high-quality high-carbon natural scaly graphite, and the graphite surface is modified by the advanced processing process, and the different fineness of production is different, and a graphite product is similar to an elliptical sphere.

The spherical graphite material has good conductivity, high crystallinity, low cost, high theoretical lithium capacity, low charge and discharge potential and flat, is currently an important part of the lithium-ion battery negative electrode material, which is domestic and foreign lithium-ion battery production Alternative products of the negative electrode material.

Spherical graphite materials have excellent conductivity and chemical stability, high charge and discharge capacitance, long cycle life, green environmental protection. Measuring the main indicators of spherical graphite qualities are:

First, physical performance indicators: including particle diameter (D50, μm), vibration density (g / cm3), specific surface area (m2 / g), moisture (%), fixed carbon (%).

Second, electrochemical performance indicators: Coulomb Efficiency (%), Charging capacity (MAH / g), cycle life (Cycles)

In the spherical graphite processing process, first, the graphite dry concentrate is coarsely crushed, trimmed, and the magnetic optional sequence of initial product spherical graphite was first, and then the purified workshop was purified to be spherical graphite (high purity).

A method of preparing spherical graphite comprising the following steps:

a). Provide graphite raw materials;

b). Alternately grinding the graphite raw material in a steam mill in a clockwise direction and a counterclockwise direction to obtain potato-shaped graphite particles;

c) .Make the potato-shaped graphite particles to the first plastic treatment in a plastic machine placed in a square grinding block medium and clockwise, and then in a shaped co-forming block medium and in a shaping machine rotating counterclockwise. Two shaping processing, prefabricated;

d) .Continuous grading of the preform to obtain spherical graphite.

Applications of Spherical Graphite Powder

Spherical graphite is made of a sheet graphite concentrate produced by graphite ore, an anode material used in a lithium-ion battery ("libs"). SPG can be sold as a coating ("CSPG") or unpackage ("USPG"). The uncoated SPG was carried out by micronization, circular and purified graphite. Almost all natural, USPG is currently manufactured in China due to low cost and environmental regulations. Although the cost of raw material is low, the labor rate is low, the environmental regulations are weak, but China has a large amount of excessive output energy in China.

 Spherical graphite (SPG) is also referred to as cell grade graphite, is a product that is the anode consumption in a lithium-ion battery. The sheet-like graphite concentrate was processed into ultra-high purity (> 99.95% C) with a particle size of 10 microns to 25 microns.

 Spherical graphite (SPG) is mainly used as a battery anode material. It is its special conductivity, making spherical graphite into key components in anode manufacturing. Graphite represents 50% of battery minerals in lithium-ion batteries. The calculating process reduces surface area to allow more graphite to enter smaller volumes. This creates a smaller and more efficient, more efficient anode product for the battery. It also increases the battery to charge and discharge.

 With the expected growth of market demand such as electric vehicles, the demand for spherical graphite is expected to increase rapidly.
