Topic: Quasi/all-Solid-State Electrolytes for Advanced Batteries

This Special Issue focuses on the latest breakthroughs in quasi/all-solid-state electrolytes to accelerate their practical application in next-generation batteries. It aims to highlight cutting-edge developments, pinpoint existing challenges, and offer perspectives on future research trajectories. We hope to create a forum for researchers across materials science, electrochemistry, and engineering to share insights and stimulate collaboration, thereby speeding up the development of safe and high-performance solid-state battery systems.

Solid-state electrolytes have garnered significant interest due to their high safety and potential for enabling high-energy-density batteries, positioning them as one of the most promising next-generation energy storage technologies. Although substantial progress has been made in material exploration and prototype development, practical applications still face numerous challenges. Issues such as high interfacial resistance, limited ionic conductivity, and dendrite growth and interfacial degradation during cycling critically affect the rate capability and cycle life of these batteries. These challenges underscore an urgent need for innovative electrolyte material design, novel interfacial engineering strategies, and in-depth mechanistic studies.

This Special Issue aims to collect cutting-edge research on quasi- and all-solid-state electrolytes, covering areas including novel electrolyte materials (e.g., sulfides, oxides, halides, polymers, and composites), interface modification and stability, ion transport mechanisms, advanced characterization techniques, theoretical modeling, battery manufacturing processes, and system-level integration into lithium-ion, lithium-metal, sodium-ion, and other metal-based batteries.
