This review focuses on filled antimony-based skutterudites, which are among the most promising thermoelectric materials. The thermoelectric properties of over 1200 compositions from more than 250 publications between 1996 and 2022 were collected and evaluated. Various figures display the dependence of peak ZT on different factors, providing insights for finding the ideal skutterudite material for practical applications.
In the present review the focus is set on filled antimony-based skutterudites as they are among the most promising TE materials. Thermoelectric properties (at 300 K and 800 K) of more than 1200 compositions from more than 250 publications from 1996 to 2022 were collected and evaluated. In various figures the dependence of the peak ZT for single-filled, double-filled and multi-filled compounds of p- and n-type skutterudites on the publishing year, the peak temperature, electrical resistivity, thermal and lattice thermal conductivity, the power factor and the fillers are displayed. Together with plots of electrical resistivity versus Seebeck coefficient and especially thermal conductivity versus power factor these evaluations etc. may help to find the ideal skutterudite material for practical applications.
