| 4 | Description | Abstract | Detailed experimental data pertaining to ionic transport and micro structural investigations on new superionic materials formed in the mixed system (SbI3)x - (Ag2WO4)1- x (0.1 = x = 0.5) have been described in this paper. Temperature-dependent electrical conductivity analysis yielded the activation energy values for various compositions as confirmed by means of frequency-dependent conductivity results as well. Evaluation of transport properties carried out in terms of ionic transport number (ti ) measurements by Wagner’s dc polarization method and silver ionic transport number ( tAg+) measurements by EMF method has revealed that a typical ti value of 0.99 along with a silver ionic transport number of 0.95 would be exhibited by the best conducting composition (SbI3)0.4 - (Ag2WO4)0.6 having the room temperature electrical conductivity of 5.7×10-2 S cm-1. The surface morphological results obtained by scanning electron microscopy (SEM) have suggested the presence of AgI micro-crystals as dispersoids within the silver oxysalt matrix formed as a result of probable solid state ion exchange reactions occurring between SbI3 and Ag2WO4 in accordance with hard and soft acids and bases (HSAB) principle. The measured open circuit voltage, OCV for an all-solid-state electrochemical cell fabricated using the best conducting composition (SbI3)0.4 -(Ag2W04)0.6 as solid electrolyte is found to be 603 mV at room temperature. |
