Abstract Recent advancements in inorganic solid electrolytes (ISEs), achieving sodium (Na)‐ion conductivities exceeding 10 ‐2 S cm ‐1 at room temperature (RT), have generated significant interest the development of solid‐state batteries (SSSBs). However, ISEs face challenges such as their limited electrochemical stability windows (ESWs) and compatibility issues with high‐capacity, high‐voltage cathode materials Na metal anodes. The success high‐performance SSSBs hinges on developing ideal that deliver high + ion conductivities, robust chemical stability, well constructed electrode/ISE interfaces. This review explores fundamental principles strategies to optimize SSSB performance by addressing related interfaces, emphasizing many interfacial are intrinsically linked ISE properties. It highlights recent research, including mechanisms Na‐ion conduction key factors influencing it, crystal structure, lattice dynamics, point defects, grain boundaries. also discusses prototyping for cell design from perspectives material defect chemistry. Additionally, identifies future opportunities advancing provides rational solutions guide research toward practical realization SSSBs.

Abstract With the growing global demand for renewable energy and increasing scarcity of lithium resources, sodium‐ion batteries have received extensive attention research as a potential alternative. Among many cathode materials batteries, polyanion are favored their high operating voltage, stable cycling performance, good safety. However, low electronic conductivity density polyanionic limit large‐scale commercial applications. To overcome this challenge, various strategies been explored to improve electrochemical performance. them, fluorine doping has proven be an effective means. In study, we systematically effects trace mass substitution on structure, dynamics, electrochemistry deeply analyzed reaction mechanisms. The analysis results show that can effectively material, thus enhancing its A large amount voltage plateau density. environmental safety challenges associated with introduction should also addressed. Overall, in further optimize structure realizing wide application high‐performance making them competitive battery technology.

Sodium-ion batteries (SIBs) have garnered significant attention as a cost-effective and sustainable alternative to lithium-ion (LIBs) due the abundance eco-friendly extraction of sodium. Despite larger ionic radius heavier mass sodium ions, SIBs are ideal for large-scale applications, such grid energy storage electric vehicles, where cost resource availability outweigh constraints size weight. A critical component in is electrolyte, which governs specific capacity, density, battery lifespan by enabling ion transport between electrodes. Among various electrolytes, composite polymer electrolytes (CPEs) stand out their non-leakage non-flammable nature tunable physicochemical properties. The incorporation NASICON (Na Super Ionic CONductor) fillers into matrices has shown transformative potential enhancing SIB performance. improve conductivity forming continuous conduction pathways reduce matrix crystallinity, thereby facilitating higher sodium-ion mobility. Additionally, these enhance mechanical properties electrochemical performance CPEs. Hence, this review focuses on pivotal roles optimizing CPEs, including conductivity, structural integrity, stability. mechanisms underlying facilitated CPE will be explored, with emphasis influence filler morphology composition By scrutinizing recent findings, underscores NASICON-based appropriate material development advanced batteries.
