The Influence of TiO2 on the Proton Conduction and Thermal Stability of CsH2PO4 Composite Electrolytes

Abstract

Composite Electrolytes (1-x)CsH2PO4/xTiO2(0≤x≤0.4) were prepared and analyzed the structural, thermal, and transport properties. We have investigated the ionic conductivity of composite electrolytes highly pressurized pellets and found that the conductivity of pure CsH2PO4 (CDP) increased three orders of magnitude at the transition temperature. The conductivity value of the composites is greater than pure CDP after 250°C. Arrhenius plots have confirmed the conductive nature of ionic conduction. The dehydration behavior and thermal stability of the materials were observed in terms of differential scanning calorimetry, thermogravimetric analysis, and differential thermal analysis, and found that the minimum weight loss for the composite 0.6CDP/0.4TiO2. The electrodes were prepared with the technique of vapor deposition.
