The status of graphite anode is difficult to shake
The demand for vehicle electrification and energy storage has been rising year by year, which has led to the rapid development of the upstream battery industry. As the key main material of batteries, anode materials are also changing with each passing day. Various new anode materials come on the scene, constantly refreshing the performance limits of batteries.
The silicon-based anode, which can be called the ceiling of specific energy (4200mAh/g), has naturally become the new role of the "silicon" anode that everyone expects. It has been piloted in a small number of electric vehicles, mobile phones, and other terminals and will also be named silicon-based in 2024, the first year of negative electrode application.
Can silicon-based anodes break out and overthrow the graphite anodes that dominate the market? From a comprehensive comparison, the silicon-based anode has a higher specific capacity. However, the "short board effect" caused by expansion, such as poor cycle life, poor conductivity, and high preparation costs, exists objectively. It isn't easy to completely replace the graphite anode in a short time. A balanced bucket player.
Of course, the current mainstream does not mean that graphite anodes can sit back and relax. Any products that do not meet the requirements of the times will face the fate of being eliminated. Whether it is in terms of performance indicators such as capacity or compliance with policy requirements for low-carbon and environmental protection, graphite anodes are seeking innovation and change and constantly exploring their potential. Shifting from mainly artificial graphite to a combination of artificial and natural graphite is the preferred strategy for graphite anodes to respond to market trends.
Artificial graphite is mainly derived from coal and coke-like substances. The degree of graphitization is not as good as natural graphite, so the specific capacity is low, and the room for improvement is very limited. Moreover, the production of artificial graphite cannot avoid the two stumbling blocks of high temperature and pollution. This is particularly incompatible with the current vigorous promotion of green and low-carbon development.
As the modification process improves, natural graphite anodes are catching up. The natural graphite modification process represented by Hua Mingsheng gives full play to the advantages of natural graphite. It not only makes up for the shortcomings of natural graphite anodes in terms of cycle and rate, but the purely physical preparation process also eliminates the high pollution of graphite anodes. The inherent impression of energy consumption has been completely reversed, leading to the transformation and upgrading of the industry and winning high praise from the market.
Under the circumstances of this ebb and flow, in the future pattern of graphite anodes, the market share of natural graphite anodes will undoubtedly jump rapidly.
Some people may think that since artificial graphite and natural graphite have their advantages and disadvantages when used as negative electrodes, wouldn't it be possible to get a perfect product by combining the two? Indeed, the mixed use of the two is called "composite graphite," which can complement each other to a certain extent and is also one of the important trends in the future development of graphite anodes.
