Lithium-ion battery copper-aluminum composite terminals are bimetallic conductive structural components utilized in the cover plates, terminals, and external connection points of prismatic or cylindrical lithium-ion batteries. Typically, through processes such as cold-press bonding, explosive bonding, friction welding, cold heading, brazing, or composite strip stamping, these components combine the high electrical conductivity of copper with the lightweight properties, low cost, and casing compatibility of aluminum. This integration facilitates low-resistance, high-strength, and corrosion-resistant connections between the battery cell's negative electrode (or connection terminal) and the external busbar. These components are primarily applied as structural elements in power batteries, energy storage batteries, light-duty power batteries, and high-rate batteries. In 2025, the global sales volume of lithium-ion battery copper-aluminum composite terminals is projected to reach approximately 4.28 billion units, with an average unit price of approximately $0.185. The capacity utilization rate is expected to be around 74.6%, and the industry's average gross margin is estimated at approximately 24.8%. Upstream enterprises primarily comprise suppliers of electrolytic copper, aluminum materials, copper-aluminum composite strips and rods, stamped parts, cold-heading blanks, sealing rings, insulation components, nickel-plating and surface treatment materials, welding consumables, molds, and automated inspection equipment. The midstream sector consists of battery structural component manufacturers, cover plate assembly companies, copper-aluminum composite material processors, and precision stamping and cold-heading specialists. The downstream sector encompasses power battery manufacturers, energy storage battery manufacturers, consumer battery manufacturers, light-duty power battery enterprises, battery PACK assemblers, and new energy vehicle OEMs. Regarding the product cost structure, copper materials account for approximately 28.6%, aluminum materials for 13.4%, and copper-aluminum composite blanks or composite processing for 17.8%. Precision stamping, cold heading, machining, and welding account for approximately 14.6%; nickel plating, cleaning, and surface treatment for 6.7%; sealing and insulation components—along with auxiliary materials—for 5.8%; automated inspection, yield loss, and quality control for 6.9%; packaging, logistics, and after-sales warranty for 3.4%; and R&D validation and customer certification amortization for 2.8%. The downstream demand portfolio encompasses square power battery cover terminals, cylindrical battery pole assemblies, energy storage battery top-cover connectors, low-resistance connections for high-rate batteries, structural components for fast-charging batteries, busbar connections for power battery packs, battery terminals for light electric vehicles, and safety-critical structural components for battery cells. The downstream client roster includes CATL, BYD, CALB, EVE Energy, Gotion High-tech, SVOLT, Sunwoda, REPT BATTERO, Envision AESC, LG Energy Solution, Samsung SDI, Panasonic Energy, SK On, Northvolt, Tesla, Toyota, Volkswagen, BMW, Stellantis, and major energy storage system integrators. In terms of market demand and business opportunities, growth is driven by policy initiatives—specifically, new energy vehicle subsidies and tax incentives, grid-connection policies for energy storage systems, power battery safety standards, green manufacturing mandates, and the localization of the battery industry supply chain. Technological innovation serves as another key driver, fueled by advancements in high-rate fast charging, low internal-resistance connections, cold forming of composite metals, high-reliability sealing, automated welding, inline resistance testing, lightweight structural design, and upgrades to large cylindrical battery platforms. Furthermore, shifting consumer demands—manifested in end-users' heightened expectations regarding driving range, fast-charging capabilities, safety, service life, cost-effectiveness, and overall vehicle lightweighting—have concentrated business opportunities for lithium-ion battery copper-aluminum composite terminals in several key areas: the capacity expansion of power batteries, the mass production ramp-up of energy storage cells, the large-scale manufacturing of large cylindrical batteries, upgrades to fast-charging battery systems, the substitution of existing components with low-resistance, high-reliability structural parts, the development of localized supply chain support, and the integrated supply of complete battery cover assemblies.

The copper aluminum composite pole of lithium batteries will be a segmented product with high technical content and quality requirements in battery structural components by 2025, and its demand is highly related to the production of power batteries, energy storage batteries, and large cylindrical batteries. With the development of battery systems towards high energy density, high rate fast charging, and high safety, traditional single metal connectors face limitations in terms of conductivity efficiency, weight, cost, and stability of heterogeneous material connections. Copper aluminum composite poles achieve low contact resistance, good welding adaptability, and better lightweight performance through material composite and precision forming processes. Therefore, they have strong application value in square cell cover plates, cylindrical battery terminals, and high rate connection structures. The core of industry competition is not only material cost, but also the bonding strength of copper aluminum interface, resistance consistency, thermal cycling reliability, sealing compatibility, dimensional accuracy, surface treatment stability, and batch yield control. The certification cycle for downstream battery factories is relatively long. Once they enter the mainstream customer supply chain, the order stickiness is strong, but the annual price drop and yield pressure will continue to exist. The future market growth will mainly come from the increase in installed capacity of new energy vehicles and energy storage batteries, while being driven by the trend of fast charging models, large cylindrical platforms, low-cost energy storage cells, and integrated battery structural components. Chinese enterprises have significant cost and response advantages in copper aluminum composite materials, precision stamping, cover plate components, and battery supply chain matching, but high-end customers still focus on long-term reliability, automated testing capabilities, and consistency management. Overall, the copper aluminum composite pole of lithium batteries is not simply a small metal component, but a key connecting component that affects the safety, conductivity efficiency, and system reliability of the battery cell. In the future, it will develop towards lower resistance, higher bonding strength, thinner and lighter design, higher automation detection, and integrated cover plate components.
