摘要：

DC ionic conductivity of the composite formed between LiNaSO4 and dispersed Na ion conductor (NaNO3) was studied. The material was prepared by the ball milled technique. X-ray diffraction and differential scanning calorimetry studies confirmed the formation of composite between the host material and the dispersoid. The experimental data indicate that addition of NaNO3 significantly improves electrical conductivity of pure LiNaSO4 in the low temperature phase. A possible mechanism of conductivity enhancement in dispersed system is interpreted in terms of the formation of space charge layer between the host material and the dispersoid in which defect concentration increases.
