LiCoO2 is well known cathode materials for Lithium ion batteries
Cycling LiCoO2-based batteries to voltages greater than 4.35 V vs. Li/Li+ causes significant structural instability and severe capacity fade.
As far as i know, for this reason , LiCoO2 can only use half(0.5) of the Li contained.
However, Is it possible to delithiate all the lithium contained in LiCoO2 when charged over 4.35 V, not considering the capacity fade or discharging???
I just want to find out if it is possible to extract all the Li from LiCoO2.

I am sure it is possible, if not considering the structural stability issue, to get the fully delithiated CoO2 form, as it is a stable compound. You can check the physical and chemical properties of CoO2 in this article:
