Zusammenfassung

Thermoelectricity allows direct generation of electricity from a heatflow without moving parts, which is of particular interest forrecovering waste heat from industry and transportation. A significantamount of this heat is emerging from very hot surfaces. For thehigh-temperature range, thermoelectric materials of high thermalstability in air are required. Semiconducting cobalt oxides have beenidentified as promising thermoelectric materials. Among these oxides,sodium cobaltate NaxCo2O4 has outstanding thermoelectric properties,but it degrades rapidly when operated at high temperature in air. T...
