| Abstract: | Introduces briefly the basic structure and properties of the Na_xCo_2O_4 oxides as thermoelectric materials and reviews the ways to improve their thermoelectric properties. Discusses both the effects of Na-site doping (with K,Sr,Y,Nd,Sm,Yb,Ca and Ag as substituents)and Co-site doping (with Ti,Rh,Mn and Ru as substituents) of the materials Na_xCo_2O_4. It is found that the effect of different elements on Na-site doping is different from that on Co-site doping. However, the investigation on the doping of Na_xCo_2O_4 is worthwhile with prospective applications. |
