We are devoted to empowering global technological innovation and energy transformation through our dedication to manufacturing high-end copper-based materials. We aspire to become a world leading innovative company specializing in high-end copper-based materials. We are a leading global innovation-driven researcher, developer, and manufacturer of electrolytic copper foil. According to the Frost & Sullivan Report, we were the world’s largest supplier of copper foil for lithium-ion batteries, or LiB copper foil, in terms of sales volume in 2025, with a global market share of 7.6%. Electrolytic copper foil, also known as elecfoil, is a key intermediate component used in manufacturing both LiB and electronic circuit boards. When utilized in LiB cells, copper foil, as a current collector, is essential for improving energy density as well as guaranteeing battery safety and durability, while also helping emit heat on the anode. Copper foil used in PCB and other electronic circuits, also known as PCB-grade copper foil, serves an important function as a conductor for transmitting communications signals. We primarily offer LiB copper foil and PCB-grade copper foil, and to a lesser extent, FCCLs. In 2025, we supplied approximately 111,985 metric tons of LiB copper foil, representing the largest global annual sales volume according to the Frost & Sullivan Report.
