SKC

● Exhibiting seven flagship copper foil products at COEX (March 11–13), offering a comprehensive view of technological evolution

●​ Introducing next-gen technologies, including current collectors for all-solid-state and lithium-metal batteries

●​ Presenting expansion possibilities from EVs to ESS, drones, robotics, and aerospace

SK Nexilis, the copper foil investment arm of SKC for secondary batteries, will participate in InterBattery 2026 at COEX in Samseong-dong, Seoul, from March 11 to 13. The company plans to unveil its world-class copper foil technology and comprehensive product lineup.

Under the theme "SK Nexilis bridges the future," the company has designed its exhibition to provide a panoramic view of the evolution of copper foil, which has advanced in sync with the rapidly changing downstream industries.

In the first section, the Highlight Zone, SK Nexilis will display a massive roll of wide-format copper foil. Measuring only 4 micrometers (\mu m) thick—about 1/30th the thickness of a human hair—the roll spans 1,400 mm in width and 5 km in length. SK Nexilis’s ability to manufacture such thin foil in wide and long formats is a core competitive advantage that significantly boosts productivity for battery manufacturers.

The second section, the Tech Zone, will showcase the company’s flagship products. Visitors can explore a diverse range of copper foil solutions, including standard foils for secondary batteries, high-strength products, and high-elongation foils essential for next-generation cylindrical batteries. The manufacturing process for these products will also be presented via video demonstrations.

The exhibition also features cutting-edge R&D achievements linked to future technologies. These include high-adhesion copper foil compatible with next-generation dry-coating battery manufacturing, corrosion-resistant current collectors for fire-safe all-solid-state batteries, and collectors for lithium-metal batteries. Through these innovations, SK Nexilis aims to demonstrate the scalability of its copper foil business beyond EV batteries into applications such as Energy Storage Systems (ESS), drones, defense, robotics, and aerospace.

"Through this exhibition, we intend to solidify our position as a leading provider of future infrastructure materials that drive mobility innovation," said an SK Nexilis official. "We will actively promote our product lineup and technological prowess to global customers and partners, expanding opportunities for technical collaboration through tailored solutions."
