Cosmo Advanced Materials, a company specializing in secondary battery cathode active materials

With the explosive growth of the market for secondary batteries known as next-generation semiconductors, Cosmo Advanced Materials specializes in secondary battery materials and manufactures and supplies high-Ni-based cathode active materials used in electric vehicles and energy storage systems, starting with high-voltage and high-density lithium cobalt oxide (LCO).
COSMO AM&T’s Strength
Cathode Active Materials Application
Cathode active materials are widely used in secondary batteries for IT, such as smartphones, tablet PCs, and laptops, as well as for medium and large-sized secondary batteries for such applications as e-bikes, electric vehicles (xEV), and energy storage systems (ESS).
Features of Cathode Active Materials
LiCoO2 (LCO)
  • High-density, high-voltage product mainly used for secondary batteries for IT
  • High energy density and long life, same volume and high density
  • Proven accumulated technology through transactions with major clients for more than 10 years (applied to state-of-the-art IT devices)
LiNiMnCoO2 (NCM)
  • It is a ternary (Ni + Co + Mn) material with high capacity due to the nickel content.
  • High-Ni cathode active material manufacturing technology for small- to medium-sized secondary batteries
  • Proven high-stability material for high-Ni cathode active materials and cost savings
