SKC's anode manufacturing subsidiary SK Nexilis announced on the 4th that it has succeeded in developing a current collector (aluminum foil that acts as a pathway for electrons) for all-solid-state batteries.
All-solid-state batteries, which replace conventional liquid electrolytes with solids, are referred to as 'dream batteries' due to their high stability. Solid electrolytes reportedly have a lower risk of fire because they do not react to temperature changes or leak due to external impacts.
The current collector developed by SK Nexilis consists of nickel (Ni) foil, nickel (Ni)-plated foil, and nickel (Ni)-alloy foil. This product, specialized for all-solid-state batteries, is designed to address corrosion issues that arise in battery components.
SK Nexilis plans to complete verification of the performance and applicability of the current collector developed this time through collaboration with OEM (original equipment manufacturer) and battery manufacturers, aiming to secure a competitive market position.
They also plan to accelerate the development of current collector products for lithium metal (Li-Metal) batteries, which are considered next-generation batteries. SK Nexilis aims to complete the development of high-functionality current collector products exclusively for lithium metal batteries by 2026 through participation in government-led projects and joint development.
