2020-11-19 11:22

Description

What is 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 main index to measure the quality of spherical graphite

One is the physical performance indicators: including particle size (D50, μm), tap density (g/cm3), specific surface area (m2/g), moisture (%), fixed carbon (%)

The second is the electrochemical performance indicators: Coulomb efficiency (%), charging capacity (mAh/g), cycle life (cycles)

The 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.
