Description

Features of spherical graphite 

Spherical graphite is made of high-quality high-carbon natural flake graphite as raw material, and advanced processing technology is used to modify the graphite surface to produce graphite products with different fineness and shape like oval spheres.

Application of spherical graphite 

Spherical graphite material has good electrical conductivity, high crystallinity, low cost, high theoretical lithium insertion capacity, low charge and discharge potential and flatness. It is an important part of lithium ion battery negative electrode material and is used as a negative electrode for lithium ion battery production at home and abroad. Material replacement products. It has excellent electrical conductivity and chemical stability, high charge and discharge capacity, long cycle life, and environmental protection.

 

Storage of spherical graphite

1) spherical graphite should be stored in a dry, ventilated place where there is no other sources of pollution (recommended: temperature ≤ 45 ° C, humidity ≤ 85%); 

2) spherical graphite should be neatly stacked, and the production batch number, date and other signs should be clearly identified; 

3) spherical graphite should be carefully Handled during transportation to avoid the damage of the packaging; products that leak out of the package must not be returned to the box.
