Guoke Tanmei New Materials (Huzhou)

Guoke Tanmei New Materials (Huzhou) Co., Ltd., also known as Carmery, is a developer and producer of carbon-based energy storage materials, established in December 2022. The company was founded by Dr. Chen Chengeng, who holds a doctorate from a joint program between the Shanxi Institute of Coal Chemistry (part of the Chinese Academy of Sciences) and the Fritz Haber Institute of the Max Planck Society in Germany. Dr. Chen, a recipient of the National Science Fund for Excellent Young Scholars and recognized in MIT Technology Review's "Innovators Under 35" in China, leads a team with deep expertise in carbon materials and electrochemistry.

The firm focuses on providing carbon-based material solutions for the lithium-ion battery, sodium-ion battery, and supercapacitor industries. Its primary products are hard carbon and porous carbon materials. The business model integrates research and development, production, and sales to serve clients in sectors such as energy storage, electric vehicles, industrial machinery, two- and three-wheeled vehicles, and consumer electronics. Revenue is generated through the sale of these advanced materials and providing customized application solutions.

Guoke Tanmei offers a range of hard carbon products, including GHC-A300, B280, and C300, developed from different raw material sources like biomass, coal, and asphalt. This multi-route approach allows the company to offer products with varying characteristics, such as high capacity, high rate capability, long cycle life, and cost-effectiveness, tailored to specific client needs. For example, their asphalt-based hard carbon has demonstrated performance comparable or superior to imported products in user evaluations, particularly in terms of cycle life, while their coal-based hard carbon presents a high-value proposition for cost-sensitive applications. The company operates a 1,000-ton industrial demonstration line for lithium/sodium battery anode materials, which completed construction in January 2024, and is establishing an advanced materials R&D and testing platform.
