Energy Material Technology Co., Ltd. is a South Korea-based specialty chemical and materials company primarily engaged in the development, manufacturing, and commercialization of precursor materials for lithium-ion secondary batteries as well as battery material recycling and refining solutions. The company operates across two primary business divisions: Battery Precursor Materials and Resource Regeneration. Its comprehensive product and service portfolio comprises high-nickel cathode precursors, including Nickel-Cobalt-Manganese (NCM) precursors and Nickel-Cobalt-Aluminum (NCA) precursors; high-purity inorganic metal salts and chemical solutions, including nickel sulfate, cobalt sulfate, manganese sulfate, and lithium carbonate; customized precursor coprecipitation and synthesis services tailored for electric vehicle (EV) and energy storage system (ESS) cathode active materials; and closed-loop hydrometallurgical recycling services, including black mass processing, metal extraction, and industrial battery scrap recovery. The company supplies cathode active material manufacturers, secondary battery cell producers, and electronic component enterprises throughout South Korea and international markets. Founded in 2010, Energy Material Technology Co., Ltd. is headquartered in Chungju, Chungcheongbuk-do, South Korea. In recent operational and strategic developments, the company has expanded its hydrometallurgical processing facilities to increase the recovery efficiency of critical battery-grade metals from recycled black mass, formed strategic supply alliances with domestic cathode active material manufacturers, and advanced the commercialization of next-generation ultra-high-nickel and manganese-rich precursor formulations to address growing global demand for high-energy-density electric vehicle battery applications.
