Graphite anode material is the ideal anode material for lithium batteries, with the advantages of high stability, good electrical conductivity, abundant resources, etc. The main types of graphite anode material are artificial graphite, natural graphite, composite graphite, etc. Among them, artificial graphite has the advantages of long cycle life, good multiplier performance, low expansion coefficient, etc., and gradually become the mainstream of the domestic market, and the market share is expanding year by year.

The production of artificial graphite goes through four major processes: crushing, granulation, graphitization and sieving, which can be further subdivided into more than ten sub-processes such as pretreatment, pyrolysis, ball mill screening, graphitization, sieving and iron removal, etc. The core process is graphitization and granulation, which has a great impact on the performance of negative electrode materials such as gram capacity and multiplier performance.

Thanks to the advantages of artificial graphite in terms of long cycle life and fast charge/discharge, artificial graphite anode materials are expected to be more widely used in the production of lithium batteries and further applied in the fields of new energy vehicle power batteries and energy storage batteries.
