Next-Generation Technologies Expanding the Energy Paradigm
SK On will participate in InterBattery 2026, Korea’s largest battery exhibition, from March 11-13 at COEX in Seoul. Under the exhibition theme “Unlock the Next Energy,” the company will showcase a broad range of innovative products and next-generation technologies tailored to evolving global market needs. The exhibition highlights SK On’s expanding portfolio beyond electric vehicles, including energy storage systems (ESS), robotics, and other emerging applications.
The booth unfolds across the categories of Leading Tech, Future Tech, and Core Tech to offer a structured journey through SK On’s current capabilities, next-generation technologies, and core product strategies.
Leading Tech | Innovation Across Battery Design and Manufacturing
Through interactive content, the Leading Tech zone introduces SK On’s key processes spanning battery design to manufacturing. Featured exhibits include a Pouch-integrated Prismatic Cell and the On-Vent Prismatic Cell, a prismatic cell structure that enables gas and heat vents to be positioned at desired locations using laser engraving technology, thereby enhancing design flexibility.
The dry electrode process, in which electrodes are manufactured using solid powder without solvents during mixing and coating, is also being showcased. SK On is currently accelerating development toward commercialization, having already completed a dry electrode pilot line in 2024.
Future Tech | Expanding the Technology Spectrum with Next-Generation Solutions
At the Future Tech zone, located at the center of the booth, next-generation technologies currently under development are being exhibited. One representative technology is the immersion cooling solution, being jointly developed with SK Enmove. With immersion cooling, heat is managed by submerging batteries in cooling fluid. At InterBattery 2026, visitors will gain firsthand access to the cooling structure through a vehicle underbody model and a compact module applying a Cell-to-Pack (CTP)-based immersion cooling design.
In addition, SK On is introducing the HYPER FAST battery, its ultra-fast charging technology capable of charging from 10% to 80% in seven minutes. Additionally, a Hyundai WIA autonomous mobile robot (AMR), which is equipped with SK On’s NCM (ternary) battery and is being used in industrial environments like Hyundai Motor Group Metaplant America (HMGMA), will be part of the exhibit. Visitors will be able to directly interact with the robot.
Core Tech | ESS and Cell-to-Pack Technologies Strengthening Competitiveness
The highlight of the exhibition is the Core Tech zone, which is placing focus on this year’s key business area: energy storage systems (ESS) and the core technologies supporting them. In response to growing global demand for large-format cells aimed at reducing costs and maximizing production volume, SK On is presenting a high-energy-density LFP pouch battery for ESS. It is also strengthening operational safety and reliability by applying an Electrochemical Impedance Spectroscopy (EIS)-based preventive and diagnostic system to a containerized ESS DC block for the first time in the industry.
Advancements in CTP technology, which eliminates the module stage, will also be introduced. Four pack solutions designed to enhance both energy density and cost competitiveness are being displayed:
- Pouch CTP
- Large-Surface Cooling (LSC) CTP
- Pouch-integrated prismatic pack
- Immersion cooling pack
LSC technology applies cooling plates to the contact surfaces between cells, improving cooling performance by up to three times compared to conventional indirect cooling methods. Meanwhile, the pouch-integrated prismatic pack houses pouch cells within an aluminum case in a pack configuration, offering both design flexibility and structural stability.
Experiencing SK On’s “Next Energy” On Site
Through this exhibition, SK On is presenting not only its battery technology capabilities but also the expansion of its application areas. By outlining a technology roadmap that extends beyond electric vehicles to ESS, industrial applications, and next-generation use cases, the company aims to further clarify the direction of “Next Energy.”
Visitors can see these developments firsthand at the SK On booth during InterBattery 2026.
