R&D Performance

  • Secondary Battery / Mid-Large Type CAN

    Aluminum Mat. + Deep Drawing Technology = xEV, ESS Case

    Explosion and fire protection, Passed Safety Test
    (shock, drop, vibration)

    Development and production of various size CAN products such as 0,4t wall thickness development
    (20 types)

    Development and possession of production facilities which make 250mm of long side length

  • Secondary Battery / Cylindrical Type CAN

    NTSN T-1 + Deep Drawing Technology

    Explosion and fire protection, Passed Safety Test
    (shock, drop, vibration)

    Applied to xEV

  • Secondary Battery / Safety Vent

    Lithium-ion type of Safety Vent for Secondary Battery Part

    When pressure rises above the internal pressure of the battery, the central Embo rises to shut off the electricity and make Gas emission by opening vent. [Safety Vent for explosion protection]

  • Secondary Battery / Square Type CAN

    Aluminum + Deep Drawing Technology

    Explosion and fire protection, Passed Safety Test (shock, drop, vibration)

    Relatively short Lead Time in the industry

  • Secondary Battery /CAP PLATE(for Press Vent)

    With 0.8t of A3003H-14 Plate, theoretical calculation of breaking pressure + Establish optimal process by performing CAE for measuring at shape of Notch Part
