South Korea Battery Materials Market (2026-2036)

The South Korea Battery Materials Market comprises materials used to manufacture lithium-ion and next-generation batteries that are produced in South Korea, for supply to Korean battery cell makers' domestic and overseas plants and to other customers. The market covers cathode active materials, including high-nickel NCM and NCMA, mid-nickel and high-voltage cathodes, LFP and LMFP, and next-generation cathodes; cathode precursors; anode materials, including natural and synthetic graphite and silicon anodes; separators; electrolytes and electrolyte salts; copper foil; lithium chemicals such as lithium hydroxide; and other materials, including aluminum pouch film, binders, and conductive additives such as carbon nanotubes. Applications include electric vehicles, energy storage systems, consumer electronics, and others. Battery cells and packs and materials produced by Korean companies outside Korea are excluded from market value, though overseas investments are analyzed. The ecosystem spans materials producers, raw material suppliers, recyclers, battery cell makers, automakers, and government agencies.

South Korea is home to three of the world's leading battery cell makers, LG Energy Solution, Samsung SDI, and SK On, and a large battery materials industry that grew rapidly to supply them, led by cathode makers EcoPro BM, POSCO Future M, L&F, and LG Chem, separator makers SK IE Technology and W-Scope, copper foil makers SK Nexilis, Lotte Energy Materials, and Solus Advanced Materials, and electrolyte makers Enchem, Soulbrain, and Dongwha Electrolyte. The government has designated battery specialized industrial complexes in Cheongju's Ochang area, Pohang, Ulsan, and Saemangeum to support the industry, and the Korea-U.S. free trade agreement allows Korean materials to count toward U.S. critical mineral and component sourcing requirements.

The market has faced a severe downturn. As global electric vehicle growth slowed, particularly among European automakers supplied by Korean cell makers, materials demand fell and metal prices declined. In the second quarter of 2024, EcoPro reported an operating loss of KRW 54.6 billion as sales fell 57.2%, EcoPro BM's operating profit fell 96.6%, and Samsung SDI, EcoPro BM's top customer, reported a 37.8% drop in operating profit. In the second quarter of 2025, POSCO Future M's operating profit fell 71.7%, L&F's operating loss widened to KRW 121.2 billion, and LG Chem's advanced materials profit fell 50.3%. EcoPro BM returned to profit in 2025 after an annual operating loss in 2024, although analysts attributed much of the recovery to the reversal of inventory write-downs and a change in the useful life of assets that reduced depreciation by about KRW 40 billion.

The industry is adapting. Korean materials makers are expanding into energy storage, where EcoPro BM's cathode sales volumes for energy storage rose 85% quarter on quarter in the second quarter of 2024, developing LFP and LMFP cathodes, localizing production in Europe and North America, such as EcoPro BM's 54,000-ton cathode plant in Debrecen, Hungary, and investing upstream in Indonesian nickel. Restructuring is also under way, with SK IE Technology agreeing in May 2026 to sell its loss-making Chinese separator unit to Semcorp for CNY 400 million. Demand for non-Chinese battery materials in the U.S. and allied markets and the development of solid-state battery materials offer longer-term growth.

In 2026, the Chungcheong region is expected to account for the largest share of the South Korea Battery Materials Market. The region's dominance is supported by its concentration of battery materials and cell production. North Chungcheong Province hosts EcoPro BM's headquarters and production in Cheongju and the Ochang area, designated as one of the government's battery specialized industrial complexes, LG Chem and LG Energy Solution facilities in Cheongju and Ochang, SK IE Technology's separator plants in Jeungpyeong, and W-Scope's separator plant in Chungju, and Sejong hosts POSCO Future M's anode materials production. In July 2023, the government designated four battery specialized industrial complexes, in Ochang in Cheongju, Pohang, Ulsan, and Saemangeum, to provide regulatory, infrastructure, and financial support, reinforcing the Chungcheong region's position as the industry's largest cluster.

However, the Jeolla region is projected to register the highest CAGR during the forecast period. The rapid growth of the region is attributed to new battery materials investments in Saemangeum, designated as a battery specialized industrial complex, where Korean and Chinese companies have developed precursor and materials projects that have been restructured to comply with U.S. sourcing rules, and in Gwangyang, where POSCO Holdings produces lithium hydroxide and POSCO Future M operates cathode production. Precursor localization and recycling are expected to drive growth in the region. Saemangeum was designated one of four battery specialized industrial complexes in July 2023, and POSCO's Gwangyang lithium hydroxide plant, with annual capacity of about 43,000 tons, provides a domestic source of lithium chemicals for precursor and cathode production in the region.

The Gyeongsang region is expected to account for a significant share of the market. Pohang in North Gyeongsang Province, designated as a battery specialized industrial complex, hosts EcoPro's battery materials campus and POSCO Future M's cathode and synthetic graphite anode production, and Daegu hosts L&F's cathode production. The region's steel and chemical industry base supports battery materials manufacturing, though producers such as L&F, whose second-quarter 2025 operating loss widened to KRW 121.2 billion, have faced difficult conditions. Pohang was designated one of four battery specialized industrial complexes in July 2023, supporting EcoPro's integrated campus spanning precursors, cathodes, and recycling.

Ulsan is expected to account for a moderate share of the market. The city, designated as a battery specialized industrial complex, hosts Samsung SDI's battery production and research, Korea Zinc's battery materials and precursor operations, and a large petrochemical and nonferrous metals industry supplying battery materials inputs. Korea Zinc's recycling and precursor activities position Ulsan to benefit from localization of non-Chinese supply chains. Ulsan was designated one of four battery specialized industrial complexes in July 2023, and Samsung SDI's target of mass-producing all-solid-state batteries by 2027 could make the city a center for next-generation battery materials demand.

The capital region and other areas are expected to account for smaller shares of the market. The Seoul metropolitan area hosts the headquarters and research centers of Korean battery and materials companies, including electrolyte and specialty materials producers such as Soulbrain and Dongwha Electrolyte, and other regions host copper foil, electrolyte, and recycling facilities, including SungEel HiTech's recycling operations. Korean cell makers' research on next-generation chemistries, including GM and LG Energy Solution's plan to commercialize lithium manganese-rich cells from 2028, is largely conducted in the capital region, shaping demand for new materials developed by nearby suppliers.
