Spherical graphite is made of high-quality high carbon natural flake graphite by using advanced processing technology to modify the surface of graphite to produce graphite products with different fineness and oval shape.
Spherical graphite material has good conductivity, high crystallinity, low cost, high theoretical lithium embedding capacity, low and flat charge discharge potential. It is an important part of the negative electrode material of lithium ion batteries and a replacement product of the negative electrode material used in the production of lithium ion batteries abroad. It has excellent conductivity and chemical stability, high charging capacity, long cycle life, and environmental protection.
In the process of spherical graphite processing, the initial product spherical graphite is formed by rough crushing, dressing, magnetic separation and other processes of dry graphite concentrate in the spherical graphite workshop, and then it is purified at high temperature in the purification workshop to become high-purity spherical graphite.
There are two main indicators to measure the quality of spherical graphite, one is physical performance indicators, and the other is chemical performance indicators. Now let's introduce the measurement standards of these two indicators:
Physical performance indicators: including particle size, specific surface area, tamping density, water content and fixed carbon.
Chemical performance indicators: Coulomb efficiency, charging capacity and cycle life.
The above is about spherical graphite for your reference. Qingdao Jinhui Graphite Co., Ltd. was established in April 2000, mainly engaged in the graphite mining and processing industry, and its products cover nearly 300 varieties of medium carbon, high carbon, high-purity, micro powder, spherical, expandable, graphene, building materials and other series, and are sold to nearly 400 enterprises in more than 20 provinces, cities, autonomous regions in China and more than 10 countries and regions abroad, It is a powerful graphite processing factory. If you need it, you can call at any time.
