Hydrothermal Synthesis and Thermoelectric Properties of New Oxides (Ca0.85-xNdxOH)1.16CoO2

doi:10.3724/SP.J.1077.2010.00669

Abstract

Abstract: Plate-like particles of (Ca_0.85OH)_1.16CoO₂ were prepared in which Nd was partially substituted for Ca to improve the thermoelectric performance. The values of Seebeck coefficient of as-synthesized oxides are all positive, showing that these oxides are p-type materials. The electrical conductivity initially decreases then increases with increasing Nd-doped amount, which is the coeffect of carrier concentration and carrier mobility. The Seebeck coefficient increases with the increasing Nd-doped amount below 473K. The power factor reaches 7.06×10^-5 W/(m·K²) at 573K for (Ca_0.75Nd_0.1OH)_1.16CoO₂.

Key words: hydrothermal synthesis, layered cobalt oxide, thermoelectric properties
