Application of Secondary Copper in Copper Foil Enterprises [[SMM Copper Conference]]

On April 24, at the CCIE-2025SMM (20th) Copper Industry Conference and Copper Industry Expo - Green Development Forum for the Recycled Copper Industry, organized by SMM Information & Technology Co., Ltd., SMM Metal Trading Center, and Shandong Aisi Information Technology Co., Ltd., sponsored by Jiangxi Copper Corporation and Yingtan Land Port Holding Co., Ltd., with special support from Shandong Humon Smelting Co., Ltd., and co-organized by Xinhuang Group and Zhongtiaoshan Nonferrous Metals Group Co., Ltd., Xie Houyuan, Purchasing Director of Shenzhen Londian Wason Technology Co., Ltd., presented on behalf of Gao Yulin, General Manager of Shenzhen Londian Wason Technology Co., Ltd., on the topic of "Application of Recycled Copper in Copper Foil Enterprises." 1. Overview of Recycled Copper Global/China annual recycled copper volume Global trend towards resource recycling Scenarios for resource conservation and cost sensitivity: shortage of primary copper resources, demand for cost reduction and efficiency improvement. Environmental and sustainable development requirements: low-carbon industries, energy-intensive industries. Policy-driven scenarios: coverage of mandatory recycling policies, compliance needs for international trade. Specific performance requirement scenarios: integrated circuit boards, communication cables; medical devices, aerospace, military. Forms of Recycled Copper Physical forms: blocks/bars (copper pipe, copper plate, copper billet); wire/cable copper; copper shavings/powder. Chemical forms: pure copper (copper cathode), copper alloys; copper oxide/copper compounds, plated copper materials. Utilization Methods of Recycled Copper Direct reuse: directly processed into new copper semis (such as copper billets, copper wires). Used for construction, power equipment repair or replacement. Advantages: no need for smelting, low cost, and less energy consumption. Smelting and regeneration: after smelting, cast into copper ingots (such as copper anode plates). Used for producing basic materials like copper wires, copper pipes, and copper alloys. High-value-added deep processing: high-purity copper materials. Used for: 3D printing metal powders, electronic industry copper foils, copper clad laminates, NEV battery connectors, etc. Compound extraction: preparation of chemical products such as copper sulphate, copper oxide. Used for agricultural fungicides, industrial catalysts. Current Status, Technical Challenges, and Future Breakthrough Directions of Recycled Copper Future breakthrough directions: intelligent sorting - increased utilization rate; innovation in green financial tools - expanded breadth and depth of recycling; alignment with international standards - global collaboration and policy support. It is expected that the industry concentration will increase to over 60% by 2030. 2. Development of the Copper Foil Industry and Copper Foil Applications High-precision electrolytic copper foil products & downstream applications Copper foil production process High-precision electrolytic copper foil refers to a product formed on the surface of a cathode roller through electrolysis, using a copper sulfate solution made from copper with a purity of over 99.9%. Copper foil applications Divided into lithium battery copper foil and electronic circuit copper foil, used respectively for the negative electrode current collector of lithium-ion batteries and the manufacturing of electronic circuits. 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% to 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-thin trend: to improve profit margins and meet customer demands, the trend towards ultra-thin copper foil will continue. It is expected that by 2025, the market share of <6μm copper foil shipments will increase to 50%. Increased demand for consumer electronics: the booming development of AI and the low-altitude economy has increased the demand for domestic high-end copper foils such as high-frequency, high-speed copper foils, raising the requirements for production processes and copper foil technology. Strengthened industry chain collaboration: cooperation among upstream equipment suppliers, midstream foil manufacturers, and downstream battery factories and automakers will help accelerate R&D and promotion, improving the efficiency of the entire industry chain. Continuous growth of NEVs: from 2025 to 2030, the proportion of new NEV sales in China will increase from 25% to 40%, driving rapid growth in the power battery market. Increased demand for ESS: in 2024, the global and Chinese ESS battery market shipment growth rates will both exceed 70%, indicating a significant increase in the ESS market. Technical Requirements for Copper Foil on Copper Materials Use of copper raw materials with technical indicators better than those of #1 copper cathode: 1. 0# copper cathode: copper content ≥99.99%, extremely high purity 2. #1 copper cathode: copper content 99.95% 3. #2 copper cathode: copper content 92% - 93% 4. Imported copper: registered and unregistered. 3. Application of Recycled Copper in the Copper Foil Industry Technical indicators that recycled copper must meet in the copper foil industry Equivalent to 0# and #1 copper cathode: Purity: required for conductivity and high-end copper foil production. Impurity content: required for conductivity and high-end copper foil production. Efficient form of copper dissolution: the shape of the copper material determines production efficiency and improves process adaptability. Form of copper material: copper rod, copper plate, or copper wire nodules (cannot be mixed). Certification requirements for recycled copper recovery 4. Summary The utilization of recycled copper is an inevitable choice for resource circulation and green manufacturing; a necessary option for decarbonization and sustainable development; and a basic need for future global market expansion. Industry development: 1. Breakthroughs in recycling technology: high-purity, alloy technology, low-cost recycling; 2. Supportive recycling policies and improved recycling systems; 3. Process optimization and industry chain collaboration by producers. In addition, it provided an introduction to the profile of Londian Wason (Shenzhen) Holding Group Co., Ltd., global capacity and market share, production site layout & applications in China, and research institutions focusing on both current and future studies. 》Click here to view the special report on the CCIE-2025SMM (20th) Copper Industry Conference and Copper Industry Expo
