On the 3rd, I-M announced that it is accelerating the mass production and export to China of composite copper foil film, a new material that can reduce the risk of thermal runaway. Since the first roll-unit composite copper foil export in January, the company is in talks with 2 to 3 other copper foil companies in China for initial supply quantities.
I-M has established a mass production system capable of continuously producing roll-unit composite copper foil film up to 5,000 meters in length, developed with proprietary technology. Through the initial roll-unit supply to Huachang in China, it has proven its technological capability and competitiveness, and plans to consider expanding production lines to prepare for increased domestic and international demand.
Composite copper foil film is a next-generation material that replaces electrolytic copper foil used for anode current collectors in secondary batteries. With excellent thermal conductivity and thin thickness, it effectively controls battery heat generation, significantly reducing the risk of thermal runaway.
An I-M official stated, "As fire accidents related to secondary batteries frequently occur domestically and internationally, strengthening battery safety has become the industry's top priority. We will strengthen our sales network and expand production in anticipation of increased interest and demand for composite copper foil film, which can reduce the risk of thermal runaway, a representative cause of secondary battery fires."
Meanwhile, in December last year, I-M strengthened its business competitiveness by acquiring a 32% stake in Topmac, a specialized advanced materials manufacturing equipment company. The company plans to create synergy in advanced materials businesses such as composite copper foil film and high-end flexible copper clad laminate (FCCL) through cooperation with Topmac.
