● SK nexilis will run a booth at the COEX Exhibition Center at Gangnam for 3 days from March 15 to 17 that will be 2.5 times bigger the size than last year’s show and will have a real-size copper foil on display.

● Introducing the overwhelming global top technology of high-elongation and high-strength copper foil, global expansion plan, and community activities for mutual growth.

SK nexilis, a copper foil business for EV batteries in which SKC (CEO & President Woncheol Park) has invested, will display a full-size copper foil that embodies the world’s best technology at InterBattery 2023, the largest industrial battery exhibition in South Korea that will be held at COEX in Gangnam-gu, Seoul for 3 days from March 15.

SK nexilis has designed a 135 square meters booth under the theme of A World-changing Technology and Indispensable Copper Foil for EV Batteries. The booth reflects the copper foil’s color and dynamics. The first zone _ title_d Welcome to SK nexilis Zone will have on display a real, factory-produced mother roll of copper foil. This full-size roll is composed of a copper foil with a thickness of 5 micrometers (㎛), 1/25 the thickness of a human hair, and a width of 1,358mm that is wound into a 48-kilometer roll and weighs up to 3.6 tons. SK nexilis is the one and only booth operator that will showcase to the public a life-size copper foil. 

SK nexilis’ technology of manufacturing a thin copper foil wider and longer strikingly raises the productivity of battery manufacturers. As the copper roll gets longer, it cost and time gets significantly lower for clients to replace a roll, thereby greatly contributing to maintaining quality. In addition, a more use of extra-wide copper foil will lead to producing wider areas of anodes in the same amount of time. 

In the New Mobility Frontier Zone, the copper foil production process is modeled for display. The entire process from melting, coating, and slitting the raw material to inspection before shipping is presented in an easy-to-understand manner that will allow both industry insiders and general public to easily understand how the product is manufactured. 

The Global No. 1 Innovator Zone will mainly feature videos to introduce SK nexilis’ products. Visitors will be offered details of each product like high-strength products which have seen a recent increase in demand due to the acceleration of the battery manufacturing process and high-elongation products that are essential for next-generation cylindrical batteries. Being the first in the world to develop a high-elongation product, SK nexilis is being well-received as the only company with a variety of copper foil product groups that cater to different battery manufacturers’ processes.

SK nexilis has leveraged its technological competitive edge and signed a big supply contract last month with Northvolt, the largest battery manufacturer in Europe, to cover almost 80% of the demand for five years from 2024. Additional negotiations are in progress with multiple global companies. At the Global Network Zone of SK nexilis’ booth, visitors will see the company’s ongoing facility expansion in Malaysia and Poland in addition to its plans to build a global production system with an annual production capacity of 250,000 tons by 2026 thus broadening its customer _ base_.

An SK nexilis executive said, “At InterBattery, we will communicate our technology and plans to build a global production system, making it easy for our major clients and industry insiders as well as the general public to understand,” and added, “People will see for themselves the overwhelming process technology embodied throughout the production process and the manufacturing technology that supports a variety of our product lineups.” [End of _ document_]​
