Carbon materials are the most widely used anode materials for lithium batteries, which can be classified into graphite materials (natural graphite, artificial graphite, composite graphite, MCMB), graphene and disordered carbon materials (hard carbon, soft carbon). Among them, artificial graphite has high specific capacity (reversible capacity 340~360mAh/g), low and stable lithium intercalation potential (0.25V~0.005V), cheap price (30~80 yuan/kg), excellent cycle The core advantages such as lifespan (up to thousands of times) are currently the commercialized anode materials with the best comprehensive performance.

In this article, we will introduce the detailed information about the top 12 graphite anode manufacturers in China, namely, they are BTR, Shanshan Technology, Jiangxi Zichen, Zhongke, Kaijin, Shangtai Tech, Xiangfenghua, Dongdao , Hubei Kuntian, BCC, JHN and Sinuo.

 

1. Natural graphite vs artificial graphite - compare from 4 perspectives

• From the perspective of energy density, natural graphite has higher gram capacity and compaction density;
• From the perspective of cycle performance, natural graphite has many surface defects, serious side reactions, poor compatibility with electrolyte, and cycle performance is not as good as artificial graphite;
• From the perspective of expansion rate, natural graphite has higher crystallinity, obvious anisotropy, and greater volume change after lithium intercalation;
• From the perspective of cost, the price of natural graphite is more than 10% cheaper than artificial graphite, the main reason is that natural graphite does not use high energy consumption graphitization process

 

2. Hard carbon vs soft carbon - which is better as anode

• Hard carbon: refers to a carbon material that is difficult to graphitize above °C. It is named for its high mechanical hardness. It is generally obtained after heat treatment at 500-°C. However, this type of material has a high irreversible capacity for the first time, and there is a voltage hysteresis. and other shortcomings. At present, the main application of hard carbon can be directly used as negative electrode material or mixed with graphite to improve the fast charging ability.
• Soft carbon: refers to carbon materials that are easy to graphitize above °C, such as needle coke, petroleum coke, carbon fiber, carbon microspheres, etc., which have a low degree of graphitization and good rate performance, but low specific capacity (250~300mAh/ g), the output voltage is low, and there is no obvious charging and discharging platform. Such materials are generally not directly used as negative electrode materials, but as raw materials for artificial graphite, or as coatings to improve the conductivity and kinetic properties of materials.

 

According to statistics from authoritative organizations, in , the global shipment of anode materials will be 1.556 million tons. From the perspective of product classification, artificial graphite is the mainstream, accounting for nearly 80%, natural graphite accounts for nearly 20%, and other anode materials account for a very small proportion.

4. Summary

Based on its excellent cycle performance and low expansion characteristics, artificial graphite has established its dominant position as anode material. The top three positions of BTR, Shanshan tech, and Jiangxi Zichen are hard to shake, representing China's natural graphite and artificial graphite respectively top level. However, artificial graphite requires ultra-high temperature for graphitization. More than 50% of its cost comes from the graphitization process, and the electricity price accounts for as much as 25%. Therefore, most of the graphitization production capacity is distributed in Inner Mongolia, Sichuan, Shanxi, and Qinghai, where electricity prices are relatively cheap. In addition, the structural transformation and process upgrade of the graphitization furnace is also one of the important directions for continuously reducing the cost of artificial graphite in the future.
