High-Voltage LiCoO2 (LCO) Powder for Li-Ion Battery Cathode, 100 g/bottle, CLIBCHVLCO

Lithium cobalt oxide (LiCoO2) is a layered cathode material used in lithium-ion batteries due to high energy density, good cycling performance, and relatively high discharge voltage. High voltage LCO (4.35V, 4.45V, or even 4.6V) can be realized by doped with traces of Aluminum, Magnesium, or Titanium, the crystal structure can be reinforced to withstand higher voltages, unlocking significantly more capacity (up to ~190 mAh/g) without collapsing.

This high-voltage LCO cathode is surface coated with single crystalline aluminum (Al).
