- SK Nexilis will showcase ultra-thin wide-width copper foil for next-generation batteries at InterBattery 2026.
- The company will also present advanced current collector technologies for solid-state and lithium metal batteries.
At InterBattery 2026 in Seoul, SK Nexilis will introduce a new generation of battery copper foil technologies designed for advanced secondary battery manufacturing. The exhibition highlights the company’s progress in ultra-thin, wide-width copper foil and specialized current collectors developed to support emerging battery chemistries and manufacturing processes. These innovations are aimed at improving energy density, durability, and performance in next-generation electric mobility and energy storage systems.
Next-Generation Copper Foil for Advanced Battery Manufacturing
During the event, the company will display a roll-form copper foil featuring a thickness of 4 μm, a width of 1,400 mm, and a length reaching 5 km, demonstrating manufacturing capability at large industrial scale. Alongside this product, SK Nexilis will present standard copper foil for secondary batteries, as well as high-strength and high-stretch variants designed specifically for next-generation cylindrical battery formats used in high-performance electrified vehicles and energy storage applications.
Emerging Materials for Solid-State and Lithium Metal Batteries
Beyond copper foil production, the company will share updates on research activities focused on future battery architectures. These developments include high-bonding copper foil compatible with emerging dry-process battery manufacturing techniques. SK Nexilis is also advancing corrosion-resistant current collectors intended for all-solid-state batteries, as well as specialized collectors designed to support lithium metal battery technologies that are expected to significantly increase energy density in upcoming electric mobility platforms.
