Synthesis of NaxCo2O4 thermoelectric oxides by the polymerized complex method

The thermoelectric oxide NaxCo2O4 was synthesized by the polymerized complex method, which provided a flaky powder. The sintered sample showed a high density, a fine microstructure and improved thermoelectric performance compared to a sample prepared by the conventional solid state reaction method.
