Abstract

A model incorporating the surface conductivity and morphology of the composite solid electrolytes is envisaged to explain their conduction behaviour. The conductivity data on LinX-50 m/o Al2O3 (X = F-, Cl-, Br-, CO32-, SO42-, PO43-) composites prepared by thermal decomposition of LinX.2nAl(OH)3.mH2O salts and Li2SO4-A (A=Al2O3, CeO2, Y2O3, Yb2O3, Zr2O3, ZrO2 and BaTiO3) composites prepared by mechanical mixing of the components are examined in the light of this model. It is surmised that the particle size of both the dispersoids and the hosts not only influence the ionic conductivity of the host matrix but also affect its bulk properties.
