SK Nexilis, an investor in SKC's copper foil business for secondary batteries, will exhibit actual copper foil featuring world-class technology at 'InterBattery 2023,' the largest domestic battery industry exhibition held at COEX in Gangnam-gu, Seoul, for three days starting from the 15th.

SK Nexilis has prepared a 135㎡ booth under the theme "Technology that changes the world, the core material of electric vehicle batteries, copper foil," reflecting the copper color and dynamism of the copper foil. In the first zone, the ‘Welcome to SK Nexilis Zone,’ the copper foil ‘Mother Roll’ produced in an actual factory is displayed. This real item is copper foil with a thickness of 5 micrometers (㎛), which is 1/25 the thickness of a human hair, wound at a width of 1358㎜ and a length of 48 km, weighing 3.6 tons. The SK Nexilis booth is the only place where the general public can see such a large copper foil in person.

SK Nexilis’s manufacturing technology that makes thin copper foil wide (wide width) and long (extra-long length) dramatically improves the productivity of battery manufacturers. The longer the roll length, the more it significantly reduces the cost and time incurred during roll replacement for customers and greatly contributes to maintaining quality. Also, the wider the copper foil used, the more anode area can be produced in the same amount of time.

In the ‘New Mobility Frontier Zone,’ the copper foil manufacturing process is exhibited through a model. All processes from raw materials to melting and rolling, slitting, inspection, and shipment are clearly represented to help both industry professionals and general visitors easily understand the product manufacturing method.

The ‘Global No.1 Innovator Zone’ is mainly composed of video content explaining SK Nexilis products. It provides detailed explanations of each product, including high-strength products that are in increasing demand due to the acceleration of battery manufacturing processes and high-elongation products essential for next-generation cylindrical batteries. SK Nexilis is recognized as the only company with a diverse range of copper foil products suitable for the manufacturing processes of various battery makers, including being the first in the world to develop high-elongation products.

Based on this technological competitiveness, SK Nexilis signed a large supply contract last month with Northvolt, Europe’s largest battery manufacturer, covering 80% of demand for five years starting in 2024, and is negotiating additional contracts with various global customers. At the ‘Global Network Zone’ of the SK Nexilis booth, visitors can check the ongoing expansion status in Malaysia, Poland, and other locations, as well as plans to establish a global production system with an annual capacity of 250,000 tons by 2026 and expand the customer base.

An SK Nexilis official said, “Through InterBattery, we will clearly communicate our technological capabilities and global production system establishment plans not only to key customers and industry stakeholders but also to the general public,” adding, “Visitors will be able to confirm our overwhelming process technology covering the entire production process and manufacturing technology supporting a diverse product lineup.”
