Multi-element doped LiCoO2 cathode

High-voltage high capacity

Synergistic doping with Ba, Mg, Ga, and Ti stabilizes the crystal structure, suppresses detrimental phase transitions and interfacial side reactions at high voltage, and improves cycling stability and rate capability of the cathode material.
