About this material
LiCoO2 has the simplest structure of the commercial cathodes: a layered framework that packs to 3.9–4.2 g/cm³, which is why it still delivers the highest volumetric energy density in thin consumer cells. First-cycle efficiency of 94–96% is the best in the family.
The limitation is stability at high voltage. Above 4.2 V cobalt dissolution and phase transition accelerate; high-voltage grades use Mg, Al or Zr doping plus surface coating to reach 4.45 V, at roughly two thirds of the cycle life. Supply it where volumetric density or a known-good baseline matters more than cost per kWh.
Documentation, controls and care
Quality controls
- Certificate of analysis per batch
- Moisture by Karl Fischer, reported per lot
- Trace metal screening
- Retained samples held for 12 months
Handling & storage
- Store in a dry environment below 30 °C, away from direct sunlight.
- Equilibrate to room temperature before opening to avoid condensation on the material.
- Dry at 60–80 °C under vacuum before use where the process requires it.
