Graphite Anode For Li-Ion Battery
Graphite has long been a key component of lithium-ion batteries. However, it has limitations. A key one is slow kinetics. This has been a major issue in the field of battery technology. But modern purification techniques have improved purity.
The use of silicon-based anodes has also been investigated. This combination has been shown to produce high capacity and low impurity. These factors are important for the production of next-generation lithium-ion batteries.
Currently, there are two types of graphite used for Li-ion anodes. These include natural graphite and synthetic graphite. Each has its own advantages and disadvantages.
There is a growing demand for anode materials in the Li-ion battery market. A graphite-based material will be a vital component in the industry. In order to meet this demand, the industry has been researching different ways to enhance performance. These methods involve treating graphite particles with ceramics and gases. This can improve the basal plane of the graphite.
Another approach is to modify the electrode-electrolyte interface. This is believed to enable fast charging of the Li-ion battery. Although the process is still in its infancy, the research is moving forward. A company called Superior Graphite has demonstrated the feasibility of this process on a pilot scale. The company is actively searching for partners who can add significant manufacturing capacities.
Another method is to use a silicon-graphite composite. This will produce significantly higher energy density over current technology. The material is expected to be in commercial operation in North America in the coming years.
