Technical Selection Guide

How should Lithium nickel cobalt aluminum oxide (NCA622) be evaluated?

Lithium nickel cobalt aluminum oxide is a cathode active material whose practical performance depends on composition, particle morphology, residual lithium, moisture, tap density, surface treatment, and compatibility with the electrolyte and upper cutoff voltage.

Why developers evaluate it

  • Cathode-electrolyte and formation screening
  • Rate, retention, and elevated-temperature studies
  • Pilot electrode and pouch-cell qualification

Development considerations

  • Confirm composition and grade-specific particle distribution
  • Match upper cutoff voltage to electrolyte stability
  • Track gas, impedance, metal dissolution, and thermal behavior

How to compare it

Compare cathode grades at matched electrode density, areal loading, N/P ratio, electrolyte quantity, and voltage window. Capacity should be interpreted together with first-cycle efficiency, impedance growth, retention, and safety behavior.
