Abstract

A new Li-ion conducting holmium based solid electrolyte by the sol–gel method was synthesized. The synthesis was carried out at low temperature compared to conventional methods by which lanthanoid silicates are synthesized. The formation temperature of the compound was found through differential thermal analysis and thermogravimetric analysis (DTA-TG). The sintered samples were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and ac impedance spectroscopy. The temperature dependence of conductivity was analysed. The experimental results show that the formation temperature of the lithium holmium silicate was found to be above 500 �C. Highest conductivity obtained was in the order of 10-4 S cm-1 at 750 �C.
