- SK Innovation Co., Ltd. engages in the refining, marketing, and distribution of petroleum products; production of petrochemicals; and development of advanced materials and batteries as South Korea's largest private energy company. Founded in 1962 and headquartered in Seoul, South Korea, the company operates through key subsidiaries including SK Energy, which refines and supplies gasoline, kerosene, liquefied petroleum gas, diesel oil, lubricants, and base oils; SK Geo Centric, which produces high-value recycled materials and petrochemical products such as paraxylene, synthetic resins, styrene monomer, and ethylene; SK On, which manufactures lithium-ion batteries for electric vehicles and energy storage systems; SK Incheon Petrochem, which focuses on safer petrochemical production; SK IE Technology, which supplies battery separators and information-electronic materials; and SK Earthon, which pursues carbon-neutral exploration and production. SK Innovation E&S, formed through the 2024 merger with SK E&S, drives LNG, hydrogen, renewable energy, and power generation across Asia-Pacific and global markets, including 13 oil fields and four LNG projects in eight countries.
The company serves automotive, industrial, and consumer markets worldwide, with refining and battery production facilities in South Korea, Hungary, China, and the United States; it targets electric vehicle manufacturers and energy providers through high-energy-density batteries, BaaS models for battery lifecycle management, and green energy solutions.
In recent developments, SK Innovation completed a major restructuring of its battery business in 2024-2025, merging SK On with high-margin SK Enmove (lubricants and immersion cooling) effective November 1, 2025, alongside integrations with SK Trading International for raw material security and SK E&S for hydrogen and LNG diversification; this created a $62 billion revenue entity with enhanced cash flow and full ownership after a $2 billion buyout of external investors. The company also advances solid-state battery commercialization through 2024 partnerships with Solid Power for sulfide electrolyte technology, targeting prototypes by 2027, and expands production capacity toward 100 GWh annually by 2025. Additionally, SK Innovation raised 5 trillion won ($3.4 billion) in 2025 via Meritz Securities to bolster financial stability amid energy transition efforts.
