Abstract
The possibility of synthesizing sulfide-conducting solid electrolytes based on the ternary sulfides MeLn2S4 doped with the binary sulfides Ln′2S3 has been approved and the influence of dopants on the electrolytic properties of the basic compounds has been investigated for the first time. The influence of the specific features of the method used for synthesizing complex sulfide phases from nanometer-sized oxide precursors on the important functional properties of the solid electrolytes has been analyzed. The samples have been examined using the X-ray powder diffraction analysis, electron scanning microscopy, and electron microprobe analysis. The region of the existence of the solid solutions has been determined, the total electrical conductivity has been studied, and the activation energy for electrical conduction for samples with different dopant contents has been calculated. The ionic and electronic transfer numbers have been determined using the modified versions of the emf method and the Hebb-Wagner polarization method. A possible mechanism of defect formation has been proposed.
