Abstract

The physical and chemical properties of the (0.76LiClO4–0.24KClO4)eut eutectic system and its heterogeneous composites with nanosized aluminum oxide powder are investigated by Raman spectroscopy, differential scanning calorimetry, and electrochemical impedance spectroscopy at different temperatures, phase states, and Al2O3 concentrations. The Al2O3 addition increased the ionic conductivity and lowered the activation energy. It is shown by the Raman spectroscopy that the addition of aluminum oxide leads to the formation of an amorphous phase, due to the lithium perchlorate crystalline phase destruction.
