Abstract

Abstract: Recently, lithium-ion conductive glass-ceramic materials have received tremendous attention owing to their high ionic conductivity, wide-ranging potential window, absence of leakage and pollution, virtuous chemical stability and non-flammable properties. The promising prospects establish them robust and efficient materials for solid state electrolyte/separator for sustaining the development of next generation lithium batteries. However, research on the glass-ceramics electrolytes is still in its initial stage, and the exciting performance offer needs further validation and fundamental exploration. Moreover, any specified review briefing the possibilities of glass-ceramic electrolytes is still missing. In the present review, we critically summarize lithium-ion conducting glass-ceramics, their synthesis methods and compositional aspects on the ionic conductivity and stability of Li batteries. The aspects of structural ionic conductivity emphasizing on migration mechanism of lithium-ion, electrode interface, and electrochemical stability are covered. The key problems and challenges of such materials are described with respect to development of optimized materials, their microstructural optimization, and promising compositions. Finally, solutions to electrode/electrolyte interface constraints are summarized, and the development prospects of such materials are updated. This review can inspire and guide researchers from a wide range of backgrounds and help to pave the way for major breakthroughs and industrial applications in the field of development of glass-ceramic electrolytes.
