4.5um Copper Foil for Lithium Batteries is an ultra-thin, high-precision current collector material with a thickness of 4.5 micrometers, specifically designed for lithium-ion batteries to maximize electrode packing density and energy efficiency. Its excellent conductivity, uniform thickness, and mechanical reliability enable improved electrochemical performance, enhanced cycle stability, and better electrode integration, making it suitable for high-capacity power batteries and portable consumer devices. In 2025, the industry’s capacity utilization rate was about 60%, while the average gross margin reached approximately 18%. Production in 2025 totaled 92,857 ton with an average price of 14,000 USD/ton. The upstream of 4.5um Copper Foil for Lithium Batteries primarily consists of high-purity cathode copper and sulfuric acid, with representative suppliers such as Jiangxi Copper, Tongling Nonferrous Metals, Freeport-McMoRan, Glencore, and BASF to ensure raw material quality and cost control. The midstream focuses on precision electrolytic deposition, thickness control, surface smoothness, and mechanical reinforcement to meet stringent battery requirements. The downstream is mainly composed of power batteries and consumer batteries, with key customers including CATL, BYD, LG Energy Solution, Panasonic, and Samsung SDI.
4.5um Copper Foil for Lithium Batteries is increasingly critical in lithium-ion battery manufacturing as demand grows for thinner, higher-energy-density electrodes and compact cell designs. Its ultra-thin profile enhances electrode packing, ensures uniform electrolyte distribution, and supports stable electrochemical performance, making it essential for high-capacity power batteries and portable consumer devices. The industry currently operates under mature electroplating and thickness control technologies, yet faces ongoing challenges from raw material cost fluctuations, process consistency, and margin pressure, leading to differentiated profitability among manufacturers. Firms capable of precise thickness control, consistent surface quality, and reliable large-scale production are better positioned to maintain operational resilience and strengthen pricing leverage, highlighting the importance of process expertise and product differentiation in shaping competitive advantage.
