Specifications vary by grade and production lot. Confirm the applicable COA or TDS, sampling method, and acceptance limits before cell qualification.

Use Cases

  • LCO is used for consumer-electronics cathode studies, high-voltage electrolyte screening, and benchmark layered oxide formulations.
  • Requested materials can be quoted for R&D, pilot-scale qualification, or production-scale sourcing after grade, particle-size, documentation, and packaging requirements are confirmed.
  • Typical supporting documents may include SDS, COA, and TDS depending on supplier lot and requested specification.

Technical Selection Guide

How should Lithium cobalt oxide (LCO) be evaluated?

Lithium cobalt 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.
