All-solid-state lithium-ion batteries (ASSLIBs) are emerging as promising alternatives to conventional batteries with liquid electrolytes due to their enhanced safety, increased energy density, and longer lifespan. However, their widespread adoption is hampered by challenges in developing effective solid electrolytes. Phosphate glassy electrolytes have attracted attention as a viable solution, offering high lithium-ion conductivity, robust chemical stability, and excellent compatibility with lithium metal anodes. This review summarizes our earlier work on phosphate glassy electrolytes for ASSLIBs, focusing on strategies to overcome critical industrial hurdles. It discusses various elements such as synthesis methods, structural properties, and electrochemical performance, with particular emphasis on enhancing ionic conductivity, mechanical resilience, and interface stability. The review also explores how these electrolytes are integrated into ASSLIB designs and interact with diverse cathode materials, and it outlines future research directions that could enable the next generation of lithium-ion battery systems to overcome existing limitations and achieve safer, more efficient energy storage.
