Supporting a sustainable secondary battery industry with high-purity and high-efficiency material technology.
Our company produces high-purity nickel, cobalt, and lithium from used batteries (NCM, LFP) using a uniquely developed CMS process. With high-efficiency leaching and solvent extraction technology, we achieve a recovery rate of over 96% and a purity of over 99.5%, establishing a recycling system of 20,000 tons of MHP and 1,500 tons of lithium carbonate annually. In addition, for doping materials in secondary batteries, particle size and impurity management are crucial. Leveraging years of technological accumulation, we have a track record of supplying to major cathode material manufacturers both domestically and internationally. Through grinding with an air jet mill system, we process inorganic materials such as oxides and hydroxides, establishing an annual production capacity of 4,000 tons. Furthermore, our high-purity alumina (Al₂O₃) with a purity of over 99.9% has low sodium content and excels in sinterability, chemical stability, heat resistance, and high thermal conductivity. It is utilized in semiconductors, display ceramics, and secondary battery coating materials, establishing an annual production capacity of 6,000 tons.
