Copper Foil Industry and Copper Foil Application Development High-Precision Electrolytic Copper Foil Products & Downstream Applications ► Copper Foil Production Process High-precision electrolytic copper foil refers to the product formed by the chemical reaction of copper with a purity of over 99.9% into a copper sulphate solution, and then produced on the surface of the cathode roller under electrolysis. ► Copper Foil Applications Divided into Lithium Battery Copper Foil and Electronic Circuit Copper Foil, used in the negative current collector of lithium-ion batteries and electronic circuit manufacturing, respectively. ► Impact on New Energy Development The thickness and performance of lithium battery copper foil directly affect the energy density and safety of lithium batteries. For example, ultra-thin copper foil can increase the energy density of lithium batteries by 5%~11%, which is significant for the driving range of NEVs. Copper Foil Capacity and Market It also introduced the capacity and market of copper foil. Future Development of Copper Foil ► Ultra-Thinning Trend: To enhance profit margins and meet client demands, the ultra-thinning development of copper foil will continue. By 2025, the market share of <6μm copper foil shipments is expected to increase to 50%. ► Increased Demand for Consumer Electronics: The booming development of AI and the low-altitude economy has increased the demand for high-end copper foil such as high-frequency and high-speed copper foil, and the requirements for production processes and copper foil technology are increasingly stringent. ► Strengthened Industry Chain Collaboration: Cooperation among upstream equipment suppliers, midstream foil manufacturers, and downstream battery factories and automakers will help accelerate product R&D and promotion, improving the efficiency of the entire industry chain. ► Continued Growth of NEVs: From 2025 to 2030, the sales share of NEVs in China will increase from 25% to 40%, driving the rapid growth of the power battery market. ► Increased Demand in the ESS Market: In 2024, the shipment growth rate of the global and China ESS battery market exceeded 70%, indicating a significant increase in the ESS market.
