Global PET-Based Composite Copper Current Collector Market Strategic Research Report

Scope of the Report

The global PET-Based Composite Copper Current Collector market size is predicted to grow from US$ 117 million in 2025 to US$ 1,295 million in 2032; it is expected to grow at a CAGR of 41.5% from 2026 to 2032.

PET-Based Composite Copper Current Collector is a lightweight lithium battery current collector material that uses PET base film as the supporting substrate and forms ultra-thin copper conductive layers through vacuum deposition and composite metallization processes. Compared with conventional copper foil, it reduces copper consumption and cell weight while maintaining electrical conductivity, adhesion, flexibility, and mechanical stability, supporting higher energy density and improved battery safety for next-generation battery structures. The capacity utilization rate in 2025 reached 60%, and the industry’s average gross margin was approximately 29%. The upstream segment mainly consists of PET base films, copper sputtering targets, and magnetron sputtering equipment, with representative suppliers including Jiangsu Shuangxing, Wanhua Chemical, GRINM Advanced Materials, and Dongwei Technology. The midstream focuses on PET film surface activation, vacuum copper deposition, multilayer composite formation, adhesion enhancement, thickness uniformity control, conductivity testing, mechanical strength verification, and roll-to-roll quality control to ensure stable electrical performance and production consistency. Downstream applications are primarily in power batteries and consumer electronics batteries, with key customers including Tesla, CATL, BYD, Samsung SDI, and LG Energy Solution. Production in 2025 totaled 4285 tons, with an average price of 28,000 USD per ton.

PET-Based Composite Copper Current Collector will be driven by battery makers’ need to reduce weight, improve safety, and raise energy density without relying solely on active material upgrades. In power batteries, its value lies in lowering copper usage and cell weight while supporting safer high-energy battery designs for electric vehicles. In consumer electronics batteries, thinner and lighter current collectors help extend runtime within limited device space. The key challenge is no longer only material performance, but stable adhesion, vacuum deposition efficiency, yield improvement, and cost control. As leading battery customers move toward lighter and safer cell structures, competition will focus on scale production consistency and customer qualification capability.
