  • - overview

    The most important components which define the capacity, voltage of the battery. Composed of Active Material, Binder, Al foil, Conductive additive


    - Al foil
















    - Strength

    Delivery date is not far behind when compared to European aluminum foil makers.
    (20 tons of Al Foil: 50 days until the arrival in EU including 2 weeks for production)

  • - overview

    Anode consists of Active Material, Binder, Cu foil, Conductive additive.
    Electrical conductivity and availability of Li-ion transfer are essential for Anode


    - Cu foil











    - Strength

    Handling the foil thickness from 6 ~ 20 mic depending on customer's request, with tensile strength of > 28 kgf/mm2.
    The elongation at both room temperature and 180 degree is below 5%. The foil has different illuminance in the surfaces as shiny and matte side with < 2 mic
    Offering copper foil with 5mic(I2S) thickness as of now.
    Being able to supply in EU market by establishing a branch and factory in Slovakia

  • - overview

    Separator keeps Cathode and Anode physically separate red for safety. Separator should be mechanically tough, but also have pores for Li-ion to transfer back and forth.










    - Strength

    Its Nano ceramic coating performs high thermal stability and high chemical resistance compared to the non-coated separator yet maintaining good electrolyte wettability. It has lower risk of internal short circuit through application of porous PO(Polyolefin) materialwhich has high permeability. It is able to process both organic solvent based and water based.
    The coating is available in both-sides and one-side upon customer's request

  • - overview

    Electrolyte carries only Li-ion, not electrons in the battery. Electrolyte is composed of organic solvent, electrolytic salt, additive for safety, Life span of battery










    - Strength

    We offer worldwide supply of electrolytes through its overseas plants in Malaysia and US and also plans to invest in EU plant in 2020 as a response to greater demand
    We have no recall for the past 10 years and dedicated to insure safety and quality by the utilization of semiconductor-grade precision analysis equipment

  • - overview

    Develoing our own test equipment for productivity and quality stabilization. The representatives of those equipment include_once Edge, Coating and Surface treatment system
    Lead Tab quality is equivalent or even better than Japanese company, Sumitomo's, who takes more than 80% of total market share around the world

    - Cylindrical Can         -Prismatic CAN & Components                        -Base plate
