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
