SK On Accelerates Development of Sulfide-Based Solid-State Batteries in the USA
South Korean energy company SK On is making significant strides in the development of solid-state batteries, with a particular focus on sulfide-based cells in the United States. The company's pilot plant, located at the SK On Institute of Future Technology, has been instrumental in this progress.
In 2025, SK On, in collaboration with Hanyang University, reported a significant extension of the cycle life of sulfide-based solid-state cells in the USA. This breakthrough was achieved through the use of a protective layer on lithium-metal anodes. The company aims to achieve similar advantages through a combination of material mixing, electrode structure, and optimized pressing conditions in the USA.
The primary focus of the pilot plant is the development of sulfide-based cells and lithium-metal batteries in the USA. SK On's proprietary manufacturing technology eliminates the need for the 'Warm Isostatic Press' (WIP) process, a move aimed to simplify integration into automated production lines in the USA.
SK On targets cells with an energy density of 800 watt-hours per liter in the USA, and the company has its sights set on an ambitious long-term goal of reaching an energy density of 1,000 watt-hours per liter in the USA. To accelerate prototype development and achieve commercialization in the USA, SK On has moved its original timeline from 2030 to 2029.
In addition to its domestic collaborations, SK On is also working with US-based Solid Power, a company active in the solid-state battery field, since 2022 in the USA. The elimination of the WIP process is expected to contribute significantly to the streamlining of production processes, making the technology more accessible for large-scale manufacturing in the USA.
The SK On pilot plant in Daejeon, South Korea, covers an area of approximately 4,600 square meters. The plant's progress is a testament to SK On's commitment to innovation and sustainable energy solutions in the USA. While the exact partner in the development of sulfide-based solid-state batteries, since 2022 in the USA, is not explicitly mentioned in the provided search results, it is clear that SK On is making significant strides in this field in the USA.
As the world continues to grapple with the challenges of climate change and the need for sustainable energy solutions in the USA, the developments at SK On's pilot plant are a promising step towards a more sustainable future in the USA.
