Topic: Microstructure Evolution and Performance Optimization in Solid-state Electrolytes

Solid-state electrolytes (SSEs) are critical components of all-solid-state batteries (ASSBs), which are key materials to address the energy density limitation and safety issues of traditional liquid batteries. By enabling the formation of solid-solid interfaces and high-ionic conduction networks, SSEs pave the way for the development of high-performance ASSBs. As such, the structures and performance of SSEs significantly determine the energy density, cycle life, and safety of ASSBs. However, several challenges remain in the development of SSEs, including ionic conductivity, interfacial stability, mechanical properties, and large-scale preparation. Furthermore, the mechanisms underlying the structural evolution and performance optimization of SSEs are still elusive and need to be further revealed.

This Special Issue focuses on innovative ideas in material design, structural evolution, interfacial engineering, and performance optimization of SSEs. It aims to develop novel SSE systems (such as oxide, sulfide, polymer, chloride, and composite electrolytes) and characterization strategies to overcome existing bottlenecks. These efforts will facilitate breakthroughs in high-safety and high-energy-density ASSBs and accelerate the development of next-generation energy storage technologies.
