§   All three form factors – pouch, prismatic and cylindrical - on display

§   High-voltage mid-nickel battery to make its debut at exhibition

§   Battery safety solutions, next-generation technologies to be featured

SEOUL -- SK On, a leading global battery and trading company, today announced it will showcase its expanded battery portfolio at InterBattery 2025, highlighting its ability to meet diverse market needs.

Under the theme “Dream Onward to the Future,” SK On will take part in InterBattery 2025, South Korea’s largest battery exhibition set to take place from March 5-7 at COEX in Seoul, to showcase products and technologies that can drive current and future industry trends.

This year, SK On, part of South Korea’s SK Group, will showcase all three types of battery form factors – pouch, prismatic and cylindrical – to emphasize its technological prowess and ability to meet diverse customer demands.

This is the first time that SK On, a renowned industry leader in high-nickel pouch batteries, is showcasing a mockup of its cylindrical battery at an exhibition. Having completed its pilot facility in the second half of last year, the battery manufacturer has been accelerating its research and development efforts on cylindrical batteries.

As for prismatic batteries, SK On is adding a top-tab prismatic cell to its exhibit collection, in addition to the side-tab prismatic cell introduced last year. The company will also showcase its Z-Folding stacking and fast charging solutions, applied to prismatic cells.

High-voltage mid-nickel cell to be exhibited for the first time

Aligning with changes in market trends, SK On will also present products with different chemistries. In particular, SK On will unveil its high-voltage mid-nickel battery for the first time, offering competitive pricing, enhanced performance, long lifespan, and improved safety.

Mid-nickel batteries refer to batteries with a nickel content of 50-70% in the NCM cathode material. They are recognized for offering a balanced combination of high energy density, similar to high-nickel batteries, and the price competitiveness and thermal stability of LFP batteries. This makes them well-suited to current market trends that prioritize cost-effectiveness.

The pouch-type high-voltage mid-nickel battery presented by SK On reduces the costly nickel and cobalt content to secure price competitiveness, while leveraging high voltage to enhance energy density.

Additionally, SK On's various technologies, including the use of electrolyte additives that protect the cathode interface, single-crystal active materials, and doping solutions that stabilize the electrode structure, enhance the stability and lifespan of the mid-nickel battery, further boosting its market appeal.

SK On will also showcase its latest technologies related to battery safety.

At the exhibition, SK On will introduce its next-generation wireless battery management system (BMS) that requires no wiring or cables. The system features wireless chips attached to the battery cell tabs, which collect data and transmit it wirelessly to the BMS via the module's antenna.

Immersion cooling technology, a result of collaboration between SK On and SK Enmove, can also be explored at this exhibition.

Immersion cooling technology is different from conventional methods that cool only the bottom of battery cells. It involves submerging the entire battery cell in special thermal fluids to effectively dissipate heat. It enhances cooling performance, enabling fast charging, while also effectively improving fire safety.

   Five exhibition zones to welcome visitors

 SK On's exhibition theme, 'Dream Onward to the Future,' reflects its ambition as a global top-tier battery company, continuously advancing toward a better future through innovation and bold aspiration.

SK On has organized its exhibition into five distinct zones.

At the main entrance, the 'Powered Cube' will immediately capture visitors' attention. Its LED display will showcase a video highlighting the future of EVs and sustainability.

Passing by the Powered Cube and entering the exhibition, visitors will encounter the first zone, Battery Performance. In this zone, Hyundai Motor’s flagship EV, the Ioniq 9, equipped with SK On's Advanced SF battery, is on display, introducing the power of SK On's battery through its V2L (Vehicle to Load) functionality. SK On’s key awards, including the Edison Awards, will also be showcased alongside various battery cells.

The second zone, Battery History, presents a chronicle of SK's battery development, from Yukong in 1982 to the post-establishment era of SK On in 2021.

In the third zone, Battery Roadmap, visitors can explore SK On's diversified battery portfolio. The display includes pouch, prismatic, and cylindrical cells, including high-voltage mid-nickel battery and long-life LFP battery.

In the fourth zone, Battery Safety, visitors can explore the next-generation wireless BMS and immersion cooling technology showcased through a model of a vehicle's underside. The upgraded “S-Pack+” with SK On's Cell-to-Pack(CTP) technology will also be on display.

The S-Pack+, a CTP format that integrates the module functions into the pack, offers cost reduction through simplified manufacturing processes and optimized product design, resulting in high marketability. Additionally, it features significantly enhanced safety, with improved electrical insulation, a structure designed to discharge gas and dust, and the application of insulation technology.

The final exhibition zone, Dream Technology, located behind the Powered Cube, showcases SK On’s next-generation battery technologies. It features the dry process, which eliminates the need for solvents in the mixing process, significantly reducing facility investment and operating costs. In addition, SK On’s polymer-oxide composite and sulfide-based all-solid-state batteries will be on display.

"SK On's strategies for diversifying battery form factors and chemistries, along with its innovative technologies in response to global EV market trends, can be explored at InterBattery 2025,” a SK On official said. “SK On will continue to strengthen its R&D capabilities and build a product portfolio that meets customer needs.”
