R&D Achievement

Direct Lithium extraction from brine

  • "Technology for extracting Lithium from brine in a short time"

    Conventional process: solar evaporation of brine, then extraction of Lithium

    Developed process: directly extracts Lithium by a chemical process

    Developed process takes less than a month to extract Lithium from brine regardless of weather conditions, and achieves high purity

Nickel hydrometallurgical extraction

  • "Technology for extracting Nickel from low-grade Nickel ore"

    Raw material : ‘limonite’, low-grade Nickel ore which is not used in the industry

    Recycles more than 90% of additives like Hydrogen, Hydrochloric acid and

    Also extracts secondary product such as Iron and Cobalt

PG-NCM cathode material

  • "High-efficiency, ecologically benign PG-NCM secondary battery cathode material development"

    Cathode material: material that stores the Lithium-ion secondary battery during discharge,

    High capacity over 215 mAh/g and Improved longevity and safety by establishing a concentration gradient
