Lithium lanthanoid silicates find importance as a solid electrolyte in high temperature lithium batteries in view of its high ionic conductivity at high temperatures. An first ever attempt is made to synthesis a new high temperature solid electrolyte viz., lithium samarium holmium silicate by sol–gel process and it has been characterized by thermal analysis (TGA–DTA), X-ray diffraction (XRD), infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). Lithium ion conductivity of 0.8087 · 10�7 X�1 cm�1 at 25 �C was obtained and it increases with increasing temperature. For the first time a highest conductivity of 0.1095 · 10�2 X�1 cm�1 was obtained at 850 �C which is high compared to other high temperature lithium battery solid electrolytes.
