摘要
Glassy electrolytes in Li2O-Al2O3-GeO2-P2O5 system with varying Al2O3 content have been obtained by melt quenching. Their thermal properties and crystallization kinetics were investigated by DSC at various scanning rates (3, 5, 10 and 15 degrees C/min). The phase composition of the samples was studied by XRD. The impact of Al2O3 addition on the Ec, molecular structure and transport properties of lithium germanophosphate glasses was investigated. The structure of the glasses was studied by IR spectroscopy. It was established the phosphate part of the glass structure undergoes modification. The conductivity of the undoped glass was found to be one order of magnitude lower compared to that of the Al-doped solid electrolytes. (C) 2021 Elsevier B.V. All rights reserved.
