Industry Overview
Electrolytic copper foil is a metal foil material made by depositing copper ions onto a cathode from an electrolytic copper sulfate solution. The raw foil must undergo a series of surface treatments based on its application scenarios to enhance performance, and is ultimately cut into finished products. It is an essential foundational material for the new energy lithium battery, electronic information industry, and other fields. Based on the core performance requirements of downstream applications, electrolytic copper foil is mainly divided into two categories: lithium battery (LIB) copper foil and electronic circuit copper foil. Depending on their thickness, lithium battery copper foils can be categorized as ultra-thin foils (<6m) and thin foils (6-10m); additionally, the tensile strength and elongation of lithium battery copper foil are key physical indicators that reflect its resistance to breakage and deformability, with high strength and good elongation ensuring downstream products are less prone to breakage during manufacturing and usage. Electronic circuit copper foil is classified into thin foil (10-18m), standard foil (>18-70m), and thick foil (>70m). The lower roughness of electronic circuit copper foil allows signal currents to flow more smoothly over the copper surface, reducing scattering and reflection, thereby lowering signal transmission loss.
The global market size for electrolytic copper foil has expanded from RMB 70.2 billion in 2021 to RMB 179.9 billion in 2025, with a compound annual growth rate (CAGR) of 26.5%. It is expected to further grow to RMB 449.2 billion by 2030, maintaining an 18.7% CAGR from 2026 to 2030. By 2025, the global market size for lithium battery copper foil is projected to reach RMB 128.4 billion, expected to grow to RMB 364.4 billion by 2030, with a CAGR of 21.1% from 2026 to 2030. The market size for PCB-grade copper foil is expected to grow from RMB 51.5 billion in 2025 to RMB 84.8 billion in 2030, with a CAGR of 10.5% from 2026 to 2030. The synchronous rapid growth of end application fieldsincluding AI and high-performance computing, drones, eVTOL, embodied AI Siasun Robot & Automation, electric engineering machinery, electric agricultural machinery, and electric vessels, as well as NEVs, ESS, and 5G/6G communicationscoupled with continuous technological upgrades, is driving steady expansion of the global electrolytic copper foil market. Among them, lithium battery copper foil benefits from the booming development of the new energy vehicles and energy storage industries, while electronic circuit copper foil benefits from advancements in AI, high-performance computing, 5G/6G communication, and embodied AI Siasun Robot & Automation technology.
