About Daejin Advanced Materials

Daejin Advanced Materials Inc. operates as a specialized manufacturer of composite materials for the secondary battery and electric vehicle (EV) industries. The company was established in January 2019 as Daejin Co., Ltd. by CEO Yoo Sung-joon and rebranded to its current name in April 2021. Yoo Sung-joon, who gained experience at an overseas component injection molding company, founded the firm to address market demand for alternatives to general-purpose plastics. The company has demonstrated significant growth, reporting an annual average growth rate of 69% in the five years since its inception. A major milestone was its listing on the KOSDAQ in March 2025.

The core of Daejin's business is the development and production of materials for secondary battery manufacturing processes. Its main product line consists of anti-static process trays and packaging materials designed for sensitive components like those in EV batteries, semiconductors, and other electronics. These products utilize the company's proprietary carbon nanotube (CNT) technology to prevent static electricity, which reduces defect rates and fire hazards during battery production. Serving a global clientele, Daejin's major customers include Ultium Cells, a joint venture between A and GM, as well as Tesla, Ford, and Hyundai Motor Group for automotive parts, and Dyson for other industrial materials. Revenue is generated through the B2B sale of these specialized materials and components.

Daejin has expanded its product portfolio to include CNT conductive materials, which are crucial for enhancing battery performance. This material offers superior flexibility and conductivity compared to traditional carbon black, allowing for significant increases in energy density with smaller amounts. The company is also entering the silicon anode market. To support its global operations and client base, Daejin has established a significant international presence with production facilities in the United States (Michigan and Tennessee), Poland, the Philippines, and Indonesia. The company plans further expansion in North America, with new plants projected for Arizona and Georgia, to better serve its OEM customers and mitigate risks associated with material degradation over long-distance transport.
