Abstract

The conductivity of the solid electrolyte based on urea and thiourea has reached 6. 84 x 10(-3) S.cm(-1) at room temperature, Analysing the conductive process of this electrolyte we found that thiourea changes into ammonium thiocyanate at a high temperature, which ionizes into ions, and can conductthe current. We obtained a red color substance through electrolysing the SPE. Analysing it with IR, UV and FAB, we confirmed that it is a polymer with a structure (SCN)(n). It is proved that the aninon is SCN-. When weadded HCl into the acetone solution of the SPE, it was found that white precipitation material appeared n the solution, which was identified as NH4Cl, so the cation is NH4+.
