How much do you know about spherical graphite?

Overview of spherical graphite
Spherical graphite is made of high-quality high-carbon natural flake graphite as raw material, and the graphite surface is modified by advanced processing technology to produce graphite products with different fineness and shape like oval spheres. The appearance color is gray black or steel gray, with metallic powder.

 
The main index to measure the quality of spherical graphite
1. Physical performance indicators: including particle size (D50, μm), tap density (g/cm3), specific surface area (m2/g), moisture (%), fixed carbon (%)
2. Electrochemical performance indicators: Coulomb efficiency (%), charging capacity (mAh/g), cycle life (cycles)
 
Application of Spherical Graphite
Spherical graphite material having good electrical conductivity, high crystallinity, low cost, high theoretical capacity of the oxide, and flat charge-discharge characteristics of a low potential, a lithium ion battery is an important part of the negative electrode material, a lithium ion battery production abroad is negative material replacement.It has excellent electrical conductivity and chemical stability, high charge and discharge capacity, long cycle life, and environmental protection.
 
The processing process of spherical graphite
In the process of spherical graphite processing, the graphite dry concentrate is first coarsely crushed, trimmed, and magnetically separated in the spherical graphite workshop to form the initial product spherical graphite, and then it enters the purification workshop to become spherical graphite (high purity) after high temperature purification.
 
 
Characteristics of spherical graphite
Good crystal orientation, high spheroidization, fewer particle surface defects, concentrated particle size distribution, high tap density, small specific surface area, and stable quality
 
The performance of spherical graphite
Low porosity, good oxidation resistance, uniform and fine structure, small void defects, moderate elasticity, easy to shape
