SK Nexilis Develops Current Collector for 'Dream Battery' All-Solid-State Battery

Performance Verification Through Collaboration with Battery Manufacturers
Focus on Developing High-Performance Current Collectors... Aiming for Market Leadership

SK Nexilis, an investment company in SKC's copper foil business for secondary batteries, has succeeded in developing a current collector for all-solid-state batteries with a lower risk of fire. All-solid-state batteries replace the conventional liquid electrolyte with a solid one, offering higher safety and are known as the "dream battery."

SK Nexilis announced on the 4th that it has newly developed a current collector for all-solid-state batteries and will verify its performance through collaboration with battery manufacturers. The all-solid-state battery, which solidifies the electrolyte, is characterized by a relatively low risk of fire due to the absence of leakage risks caused by temperature changes or external shocks.

The newly developed current collectors for all-solid-state batteries include nickel (Ni) foil, nickel (Ni)-plated foil, and nickel (Ni)-alloy foil. These products are specialized for all-solid-state batteries and are designed to solve corrosion problems occurring in battery components. SK Nexilis plans to complete performance verification and explore application possibilities of the newly developed current collectors through collaboration with original equipment manufacturers (OEMs) and battery manufacturers, aiming to secure market leadership.

Efforts are also being accelerated to develop current collector products for lithium metal (Li-Metal) batteries, which are considered next-generation batteries alongside all-solid-state batteries.

Based on its proprietary recipe technology, SK Nexilis plans to complete the development of high-performance current collector products dedicated to lithium metal batteries by next year. To this end, it is participating in a government-led national project for next-generation battery development, collaborating with multiple companies in the battery and materials alliance.

An SKC official stated, "Based on SK Nexilis's overwhelming manufacturing technology, we will supply the best products that meet the demands of next-generation battery customers," adding, "We will continue to pursue product diversification through ongoing research and development (R&D) to overcome the electric vehicle chasm (temporary demand slowdown)."
