| Abstract: | New solid electrolytes based on urea and thiourea have been synthesized. Their ionic conductivity detected by electronic conductivity instrument is higher than 6.84×10-3S·cm-1at room temperature. The main factors influencing the ionic conductivity are analyzed. These are amorphous solid solution. The thiourea changes to ammonium thiocyanate, which can ionize and conduct in the solid electrolyte. |
