Lithium aluminum germanium phosphate [LAGP] glass–ceramics have been extensively investigated because of their potential applications as electrolytes in energy storage devices and electrochemical sensors, owing to their excellent lithium ionic conductivity, high mechanical strength and low atomic mass of lithium [1], [2] and [3]. However it is not easy to fabricate large-scale homogenous LAGP glass–ceramics with high ion conducting properties, which restrains their application in all-solid-state lithium-ion battery [4] and [5]. Therefore, it is significant to study crystallization kinetics to control nucleation and crystallization processes in the fabrication techniques of LAGP glass–ceramics. The properties of glass–ceramics are dependent on chemical composition and thermal history. It is therefore important to gain a thorough understanding of the processes in the crystallization of the glass–ceramics.
The aim of the present work is to investigate the effect of various Al2O3 contents on the thermal properties, crystallization behavior, microstructures and conductivity of LAGP glass–ceramics.
