Spherical graphite

Issuing time:2018-11-19 Popularity:577

Spherical graphite is made of high-quality natural flake graphite as raw material, and is modified by advanced processing technology. It produces different fineness and looks like elliptical sphere. It is a replacement product for anode materials for lithium ion secondary battery production at home and abroad. Performance: Excellent electrical conductivity and chemical stability, high charge and discharge capacity, long cycle life, and environmental protection.

The main indicator for measuring the quality of spherical graphite

First, physical performance indicators: including particle size (D50, μm), tap density (g / cm3), specific surface area (m2 / g), moisture (%), fixed carbon (%)
Second, electrochemical performance indicators: Coulomb efficiency (%), charging capacity (mAh / g), cycle life (cycles)

Spherical graphite material has good 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 anode material and is a negative electrode for lithium ion battery production at home and abroad. Replacement of materials. It has excellent electrical conductivity and chemical stability, high charge and discharge capacity, long cycle life and environmental protection.

In the spherical graphite processing process, the graphite dry concentrate is firstly shaped into spherical graphite by coarse crushing, trimming and magnetic separation in a spherical graphite workshop, and then purified into a spherical graphite (high purity) after being purified at a high temperature in a purification workshop.
