Carbon materials

The company's carbon materials business is mainly operated by "Graphene New Energy" and is one of the earliest enterprises in China to apply graphene in bulk. Currently, it is in the first tier of the industry in terms of production and sales scale, customer recognition, research and development capabilities, and its main products include carbon nanotube conductive agents and graphene conductive agents, graphitization processing, and silicon-based negative electrode materials.

The company has successfully overcome the challenge of large-scale preparation technology that balances high quality and low cost, and has developed a stable production technology solution for single-walled carbon nanotubes. At the same time, a technologically advanced integrated research and development production system for silicon-based negative electrode materials has been established, and a complete supply chain and research and development system for conductive agents such as catalysts, carbon nanotube powders, high-purity powders, conductive slurries, and NMP recovery have been continuously improved.
