Description
Thermodynamic calculation method was adopted to predict the reaction mechanism of LiCoO2 prepared by hydrothermal-electrochemical process. It was found that in the Co-LiOH-H2O system, Co was oxidized to HCoO2-, Co(OH)2 (100 oC) or CoO (150 oC), CoOOH in sequence with the increase of electrode potential, then the ion-exchange reaction of CoOOH and lithium ion occurred and LiCoO2 came into being. The optimum synthesis parameter was obtained through thermodynamic calculation and it was validated experimentally by cyclic voltammogram method
