“…The addition of the second phase in an ISE, such as TiO 2 , Al 2 O 3 , Au or Mg, can also significantly limit the overgrowth of Na dendrites, thereby improving the stability and service lifespan of SSMBs. 146,256 Fig. 9f shows Na 3 Zr 2 Si 2 PO 12 (NZSP), which was prepared by using a traditional solid-state sintering process.…”

“…Driven by the emerging need for large-scale energy storage, Na-ion batteries are considered the ideal battery system to replace the existing Li-ion batteries with their abundant reserves and low prices. − However, traditional Na-ion batteries using organic electrolytes present safety issues, and conventional hard carbon anodes cannot meet high energy density requirements. , High-performance solid-state sodium–metal batteries (SSSMBs) with solid-state electrolytes (SSEs) are considered the ideal new-generation Na-ion batteries because they can apply high-energy-density Na-metal anodes and high-voltage cathodes. Among various types of SSEs, including polymers, , sulfides, , halides, and oxides, − etc., the sodium superionic conductor oxide SSEs , (usually indicated as NZSP, Na 1+ x Zr 2 Si x P 3– x O 12 ) have gained extensive prominence owing to their high ionic conductivity, wide electrochemical window, and good chemical compatibility with Na metal. Although the NZSP-based SSSMBs boast impressive advantages, the issues of poor solid–solid contact between sodium metal and NZSP, inhomogeneous sodium deposition, − and slow migration of bulk-phase sodium , still hinder the practical application of SSSMBs.…”

The application of sodium anodes is essential for developing highenergy density, low-cost, and high-security solid-state sodium−metal batteries (SSSMBs) to replace commercial lithium ion batteries. However, poor interface contact, high resistance, and dendrite growth between the sodium anode and solid-state electrolyte (SSE) have hampered the application of SSSMBs. Herein, an ultrastable composite sodium anode with gradient ion-electron conductive phases was constructed through the in situ conversion and alloying reaction between SbF 3 and sodium. The tightly contacted solid−solid interface between the composite anode and sodium superionic conductor oxide SSE is enriched with NaF and inside the anode is enriched with Na 3 Sb, which can inhibit the growth of sodium dendrites and accelerate the transport of bulk-phase sodium to the interface. Benefiting from these advantages, both symmetric and full cells assembled with such composite electrodes display excellent electrochemical performance. These results offer a novel composite anode design for the practical application of SSSMBs.

Inorganic all‐solid‐state sodium batteries (IASSSBs) are emerged as promising candidates to replace commercial lithium‐ion batteries in large‐scale energy storage systems due to their potential advantages, such as abundant raw materials, robust safety, low price, high‐energy density, favorable reliability and stability. Inorganic sodium solid electrolytes (ISSEs) are an indispensable component of IASSSBs, gaining significant attention. Herein, this review begins by discussing the fundamentals of ISSEs, including their ionic conductivity, mechanical property, chemical and electrochemical stabilities. It then presents the crystal structures of advanced ISSEs (e.g., β/β′′‐alumina, NASICON, sulfides, complex hydride and halide electrolytes) and the related issues, along with corresponding modification strategies. The review also outlines effective approaches for forming intimate interfaces between ISSEs and working electrodes. Finally, current challenges and critical perspectives for the potential developments and possible directions to improve interfacial contacts for future practical applications of ISSEs are highlighted. This comprehensive review aims to advance the understanding and development of next‐generation rechargeable IASSSBs.This article is protected by copyright. All rights reserved
