with that without doping elements. The maximum value of power factor is 2.26×10-4W·m-1·K-2 in case by doping with Sr (y=0.1) and is increased by 50% compared with that without doping with Sr. The thermoelectric property of NaCo2O4 after doping with Sr is the best. The experimental results show that the appropriate doping elements and doping amount can improve consumedly the thermoelectric properties of NaCo2O4......
