SK On, the battery unit of SK Innovation Co., is intensifying its focus on next-generation battery technologies, aiming to reclaim market leadership through strategic collaborations with global automakers. Park Kisoo, head of the company's R&D arm, revealed in an interview on August 3, 2025, that the company is actively pursuing partnerships with industry giants like Ford Motor Co. and Hyundai Motor Co. to advance its cutting-edge solutions, particularly in thermal management. This aggressive push is designed to enhance battery efficiency across critical sectors, including electric vehicles (EVs), energy storage systems (ESS), and high-demand AI data centers, positioning SK On to challenge dominant rivals in the competitive South Korean and Chinese markets.

A cornerstone of SK On's strategy is the refinement of its thermal management capabilities, with a significant emphasis on immersion cooling technology. This innovative approach involves submerging battery cells in a dielectric fluid, which more efficiently dissipates heat compared to traditional air or liquid cooling systems. Park Kisoo stated that this technology is crucial for improving the performance, longevity, and safety of batteries, especially in high-power applications where thermal runaway is a concern. The enhanced thermal stability is expected to enable faster charging rates and extended operational lifespans for battery packs.

The global battery market remains intensely competitive, with companies like CATL and LG Energy Solution holding significant market shares. SK On's move to partner with major automotive players underscores a strategic pivot to leverage co-development for faster innovation and market penetration. Discussions with Ford and Hyundai highlight the automotive industry's demand for more efficient and robust battery solutions to support the rapid expansion of electric vehicle fleets. These collaborations are anticipated to accelerate the commercialization of SK On's advanced technologies, providing a competitive edge in performance and reliability.

Beyond electric vehicles, SK On's immersion cooling technology holds substantial promise for energy storage systems, which are vital for grid stability and renewable energy integration. The ability to manage heat effectively in large-scale battery installations is paramount for their efficiency and safety. Furthermore, the application of this technology to AI data centers, which consume vast amounts of energy and generate significant heat, represents a nascent but high-growth market opportunity. The R&D chief's comments suggest a multi-faceted approach to market expansion, leveraging technological superiority to capture value across diverse high-demand sectors. This strategic investment in R&D is critical for SK On to differentiate its offerings and secure long-term growth in the evolving clean energy landscape.
