Using high quality natural flake graphite as raw material， Spherical graphite is made through advanced processing technology to modify the surface of graphite, and then graphite products with different fineness and spherical forms are produced.
The main indexes to measure the quality of spherical graphite
Spherical graphite material has good conductivity, high crystallinity, low cost, high theoretical lithium capacity, charge discharge potential is low and flat, is present as an important part of anode materials for lithium ion batteries, is the product of anode materials for lithium ion battery production at home and abroad. It has excellent electrical conductivity and chemical stability, high discharge capacity, long cycle life, green environmental protection. Spherical graphite processing: first in the workshop will workers dry spherical graphite graphite concentrate by crushing, dressing, magnetic separation process to form the initial product, then it is purified under high temperature in purification workshop to become spherical graphite (high purity).
The physical performance indicators: including particle size (D50, m), g/cm3 (density), specific surface area (m2/g), moisture (%), fixed carbon (%)
Electrochemical performance indicators: coulomb efficiency (%), charge capacity (mAh/g), cycle life (cycles)
