“…For instance, it has been reported that an ultrathin TiO 2 coating on NZSP can improve NZSP wetting and decrease interfacial impedance (Figure 10e). [ 171 ] Therein, the Na x TiO 2 interphase with high ionic conductivity not only results in a uniform Na plating/stripping but also prevents dendrite formation. Besides, heat treatment is another simple and promising technique to construct a Na‐ion deficient surface on NZSP for good contact.…”

Sodium metal anodes have attracted significant attention due to their high specific capacity (1166 mA h g −1), low redox potential (−2.71 V vs the standard hydrogen electrode), and abundant natural resources. Nevertheless, unstable solid electrolyte interphases (SEI) and uncontrolled dendrite growth critically hinder their commercialization. Notably, SEIs play a critical role in regulating Na deposition and improving the cycling stability of rechargeable Na metal batteries. Recently, SEI research on Na metal anodes has been intensively conducted worldwide; thus, a comprehensive review is necessary. Herein, initially, the fundamentals of SEI and the related issues induced by its intrinsic instability are discussed. Thereafter, advanced characterization techniques that unveil the morphological evolution and interfacial chemistry of Na metal anodes are presented. Subsequently, efficient strategies, including liquid electrolyte engineering, artificial SEI, and solid-state electrolyte technology, to stabilize SEI films are outlined. Finally, key aspects and prospects in the development of SEI for Na metal anodes are highlighted. It is believed that this review will serve to further advance the understanding and development of SEIs for Na metal anodes.

“…In situ measurement is possible either inside the XPS chamber or in vacuum chamber by connecting an ultrahigh vacuum transfer system to the XPS chamber. [ 62 ] The interfacial contact properties between SSEs and electrode materials can be studied during the interface formation in an experiment by repeating XPS measurement and electrode film deposition in several steps. Thus, in situ XPS is utilized to monitor this variation of interface.…”

The interface is a critical factor of electrochemical performance for all‐solid‐state batteries (ASSBs). Comprehending the composition, structure, morphology, and their evolution in the interface during charge/discharge cycling is greatly important for the development and practical application of ASSBs. The characterization techniques are very crucial and powerful for investigating the interface properties of ASSBs. This review briefly describes how the interface is generated in ASSBs, and then emphatically summarizes some important advanced techniques used to characterize the interface in ASSBs. The principle, advantage, and application of the techniques in the interface investigation are systematically discussed. This review provides fundamental insights and perspectives for developing the characterization techniques to deeply understand the interfacial behaviors of ASSBs, which is valuable for accelerating the commercialization of ASSBs used in electronic devices, electric vehicles, and large‐scale energy storage.

“…SSSBs are always plagued by low rate capability and inferior overall cycling properties resulting from the poor interfacial stability between electrodes and SSEs. [41,64] Hence, the associated stability issues, which can extremely affect charge transfer kinetics, interfacial resistance, and the electrochemical performance of cells, are urgently need to be focused on. [65] By investigating the chemical stability of two inorganic electrolyte materials termed Na-β″-Al 2 O 3 and Na 3 PS 4 , it can be concluded that due to the formation of interphase compounds with inferior ionic conductivity in Na 3 PS 4 based SSSBs, the Na 3 PS 4 electrolyte is less stable against Na anode than that of Na-β″-Al 2 O 3 (Figure 2a).…”

“…[ 90 ] In this regard, by introducing a TiO 2 film as an active interphase in SSSBs, the electrostatic potential formed at the electrode/electrolyte interface can effectively reduce the electronic conductivity and thus prevent the growth of sodium dendrites. [ 64 ] At the cathode side of a room‐temperature SSSB, a cathode‐friendly poly(acrylonitrile) (PAN) serves as a polymer matrix into which a NASICON‐type ceramic SSE powder is incorporated toward both the enhancement of ionic conductivity and the prevention of Na dendrite from penetrating through the electrolyte membrane. [ 33 ] Based on polymer electrolytes, the solid‐state recharge batteries can avoid safety issues and realize higher energy density; but due to the low room‐temperature ionic conductivity, poor mechanical properties, and weak interfacial compatibility between electrode and electrolyte, development and practical applications of polymer electrolyte based SSSBs are still limited.…”

although some promising solutions have been proposed in battery design, traditional NIBs with organic liquid electrolytes are plagued by safety issues and limited energy density. [9] For instance, the high reactivity of metallic Na with organic liquid electrolytes and dendrite formation in the process of Na metal deposition can result in inferior electrochemical performance of cells. [10-14] Moreover, the low melting point of Na at 97.7 °C have been demonstrated to be a safety hazard, which may impede further applications of sodium metal-based batteries. [4] Therefore, fabricating cells with solid-state electrolytes (SSEs) rather than organic liquid electrolytes will constitute a significant step toward novel batteries, and solid-state sodium batteries (SSSBs) will also be an innovative approach to fully inherit the merits of both metallic Na and SSEs. [15-18] With the introduction of SSEs, safety issues originating from leakage and flammability of organic liquid electrolytes will no longer impede the development of sodium metal-based batteries and thus make them to be safer battery systems. [19-22] In addition, due to the slower reactivity of SSEs against electrodes, SSSBs can deliver a long cycle life and show great merit for successful operation of cells. [23,24] Versatile geometries originating from the nature of SSEs are also of prime significance to tailor battery properties. [25,26] To note, the solid polymer electrolytes (SPEs), gel polymer electrolytes (GPEs), and many derivatives of the abovementioned materials, which inherit the merits of both liquid-like solvating environments and the dimension stability, in a deeper perspective, belong to an intermediate class between the liquid-state and true solid-state. [27,28] In principle, exemplary cases of inorganic SSEs mainly include Na-β/β″-Al 2 O 3 , Na superionic conductor (NASICON), and sulfide electrolytes. [16,29-32] The introduction of such electrolytes will not only help effectively improving the safety of battery systems, but also open up the possibility of assembling a SSSB with high-voltage positive electrode at room temperature. [33] Nonetheless, the development of SSSBs is hindered by some severe challenges, and plenty of possibilities are waiting to be explored to reach the full potential of them. [34-36] Gas evolution issues, which originates from cathode materials and will result in safety concern and aging issues to cells, still exist in SSSBs. [37,38] Moreover, based on initial conjectures, the properties of SSSBs are expected to without being hampered by dendrite penetration, but recent studies have demonstrated the contrary belief. [39] Aside from the aforementioned obstacles, Solid-state sodium batteries (SSSBs) are considered as promising candidates for next-generation energy storage applications due to the probability to achieve safer and higher energy density characteristics. However, though SSSBs can avoid using combustible organic liquid electrolytes, the development of such novel batteries is hindered by some critical challenges. P...
