Abstract: Introduces briefly the basic structure and properties of the NaxCo2O4 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 NaxCo2O4. 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 NaxCo2O4 is worthwhile with prospective applications.
