LiCoO₂ and Na_xCoO₂ 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 Na_xCoO₂ single phase using the hydrothermal method was rather difficult, and Na_xCoO₂ was usually accompanied with secondary phase of Co₃O₄.
