NCA

NCA
As the only Ni-rich, high-end material in Korea, NCA retains the highest reversible capacity among the existing LiB cathode materials.
We are capable of mass-producing NCAs through NCA modeling according to the customer’s requirements. In addition to this, we have
invested in single crystal production at CAM 7 to minimize particle cracks that may be generated when forming electrodes, which is
apparently the limitation of the existing polycrystal cathode materials. We are preparing to manufacture quality products with improved
charging/discharging efficiency and extended battery life.

Single Crystal
• As a material with maximized energy density, it does not break or damage during cell processing with no reaction to external stimuli.

Advantages Disadvantages

• Long life span • Rise in firing temperature resulting in increased processing
• Less gas and increased thermal stability expenses
• Increase in density of mixture → increase in volume • Increase in the degree of hardening
• More difficult to carry out the disintegration process

Polycrystal vs. Single Crystal Cathode Materials

Type Polycrystal Single Crystal

Volume Low High (About 30% higher when compared to Polycrystal)
Stability Low (much gas emission) High (little gas emission)
Life Span Short Long
