Abstract: The ion conduction in Zn 4 Sb 3 was investigated to determine the potential of Zn 4 Sb 3 as a thermoelectric element. Various temperature differences and electrical currents were applied and the resulting voltages were monitored for 1 h. The thermoelectric elements were analyzed after the tests by scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM/EDX), resistance scanning, and Seebeck coefficient mapping. Zn ions migrated in the current direction and formed a ZnSb layer; the thickness was proportional to the current density and strongly dependent on the temperature.
