LiCoO2 and NaxCoO2 were synthesized through the ion-exchange reaction of CoOOH using the hydrothermal method. The LiCoO2 single phase was obtained at 170°C for 12h in LiOH solutions (≥ 0.1mol/1)- The precipitated LiCoO2 had trigonal symmetry (R3̄m) corresponding to the high temperature phase of LiCoO2. The precipitate had a hexagonal plate-like shape and the size was between 100nm and 1.5nm Synthesis of NaxCoO2 single phase using the hydrothermal method was rather difficult, and NaxCoO2 was usually accompanied with secondary phase of Co3O4.
