Abstract
A preparation method for a spherical graphite for lithium batteries firstly adopts a combination of primary pulverization, secondary pulverization and shaping to produce spherical graphite with Dof 13-25 μm, and then adopts a combination of ultrafine primary pulverization, ultrafine secondary pulverization and shaping to produce spherical graphite of small particle size with Dof 3-12 μm from tailings produced during the production of spherical graphite with Dof 13-25 μm for the first time. The method increases the utilization rate of graphite raw materials by 25-35%, and can prepare spherical graphite with Dof 13-25 μm and spherical graphite with Dof 3-12 μm at the same time. An alternative method adopts a combination of primary pulverization, secondary pulverization, ultrafine primary pulverization, ultrafine secondary pulverization and shaping to produce spherical graphite of small particle size with Dof 13-25 μm directly from raw materials for the first time.
