Development of Lithium Metal Rechargeable Batteries

  • Development Steps
  • Li-S Battery Advantage
    • Anode material with the highest theoretical capacity among solid cathode materials (1,675mAh/g)
    • Relatively low operating voltage, lower cost than conventional cobalt (Co).
    • Sulfur is less toxic and more environmentally friendly than conventional material.
    • High energy density 2-3 times higher than LIB
  • Retained Competence and Development Plan
    • Research to improve life characteristics
    • Research to the electrode reaction occurring at the solid-liquid interface
    (Surface composition of carbon, three-dimensional structure, carbon content in cathode)
    • Development of electrolyte solution related to poly sulfide
    • Development of cathode structure and binder by volume change of cathode active material
    • Research to increase the reversibility of lithium metal
  •  Patents (related to Li-S battery and Lithium metal-based battery)
  • Application
    Lithium sulfur batteries (Li-S) have the potential to be used in various applications where high energy density and low cost are required.
