Abstract

NH₄PO₃-PTFE inorganic-organic composite electrolytes were prepared. Their phase compositions, thermal stability and morphologies were investigated. The composites obtained demonstrate improved thermal stability comparing with commercial NH₄PO₃. The morphology of pellets under the same conditions shows the smoother and denser surface with more PTFE content added. The conductivity was measured by ac impedance spectroscopy under different atmospheres. The composites were found to exhibit a higher conductivity in humid 5% H₂/Ar compared with open air atmosphere. A maximum conductivity of 2.3 mS/cm is obtained at 250 °C for NH₄PO₃-PTFE (volume ratio = 2:1) sample in humid 5% H₂/Ar. © 2009 Elsevier B.V. All rights reserved.
