In a word, although high capacity retention could keep after one cycle for LCO at high voltage up to 4.8V, the capacity fading will quickly take place at long-cycle applications. It is still very tough to apply LCO at HV (>4.5V), and the irreversible O3→H1-3→O1 phase transitions over 4.5 V remain an urgent technical bottleneck to overcome.
