“…However, chemical stability does not inevitably induce low interfacial resistance, which is correlated to surface chemistry and wettability [114] . As it can be seen on the number of reviews regarding interface modifications for different SEs, [15,16,18–21] a paradigm shift has happened: The performance of solid‐state cell systems is not limited by the ionic conductivity of the solid electrolyte (SE) anymore but by the insufficient interface contact between the rigid SE with both of its adjacent electrodes. Intimate contact for sufficient charge transfer over the electrode/electrolyte interfaces, in tandem with mechanical and structural stability are key requirements for a well‐performing cell.…”

“…On the other hand, sodium‐ion batteries (SIBs) still rely on organic, flammable electrolytes which leads to safety challenges comparable to LIBs. Solid‐state batteries (SSBs), based on solid electrolytes (SEs), offer a solution to the aforementioned problems and are seen as next‐generation batteries, as they promise excellent thermal stability, low flammability, high safety, high specific energy as well as long cycle life [12–22] . Meanwhile, R&D on already commercialized cell systems with sodium as the negative electrode and sodium‐beta alumina as solid electrolyte continue.…”

Sodium‐based batteries are promising post lithium‐ion technologies because sodium offers a specific capacity of 1166 mAh g−1 and a potential of −2.71 V vs. the standard hydrogen electrode. The solid electrolyte sodium‐beta alumina shows a unique combination of properties because it exhibits high ionic conductivity, as well as mechanical stability and chemical stability against sodium. Pairing a sodium negative electrode and sodium‐beta alumina with Na‐ion type positive electrodes, therefore, results in a promising solid‐state cell concept. This review highlights the opportunities and challenges of using sodium‐beta alumina in batteries operating from medium‐ to low‐temperatures (200 °C–20 °C). Firstly, the recent progress in sodium‐beta alumina fabrication and doping methods are summarized. We discuss strategies for modifying the interfaces between sodium‐beta alumina and both the positive and negative electrodes. Secondly, recent achievements in designing full cells with sodium‐beta alumina are summarized and compared. The review concludes with an outlook on future research directions. Overall, this review shows the promising prospects of using sodium‐beta alumina for the development of solid‐state batteries.

“…A series of strategies have been approached to improve the interface contact between metal electrodes and oxide ceramic electrolytes 14 , 15 . Static pressing was mostly employed to improve the physical contact between the metal anode and solid-state electrolyte to a certain extent, but the improvement effect of interface contact with acceptable interface impedance is limited 16 .…”

Improving the alkali metal electrode/inorganic solid electrolyte contact via room-temperature ultrasound solid welding

The combination of alkali metal electrodes and solid-state electrolytes is considered a promising strategy to develop high-energy rechargeable batteries. However, the practical applications of these two components are hindered by the large interfacial resistance and growth of detrimental alkali metal depositions (e.g., dendrites) during cycling originated by the unsatisfactory electrode/solid electrolyte contact. To tackle these issues, we propose a room temperature ultrasound solid welding strategy to improve the contact between Na metal and Na3Zr2Si2PO12 (NZSP) inorganic solid electrolyte. Symmetrical Na|NZSP | Na cells assembled via ultrasonic welding show stable Na plating/stripping behavior at a current density of 0.2 mA cm−2 and a higher critical current density (i.e., 0.6 mA cm−2) and lower interfacial impedance than the symmetric cells assembled without the ultrasonic welding strategy. The beneficial effect of the ultrasound welding is also demonstrated in Na|NZSP | Na3V2(PO4)3 full coin cell configuration where 900 cycles at 0.1 mA cm−2 with a capacity retention of almost 90% can be achieved at room temperature.

“…[ 24–26 ] This has presented serious challenges to the constructed interlayer in decreasing the thickness and redistributing the transported electron/ion to alleviate spatial/temporal aggregation, thus resulting in ameliorative polarization and stable electrode‐electrolyte interface. [ 27 ] Unfortunately, the ideal homogeneous and even isotropic interlayer has rarely been reported until now, making the integrated solid‐state batteries far from practical application.…”

Inorganic solid‐state electrolyte (SSE) based Na‐metal batteries have received extensive attention in next‐generation lithium‐free energy storage systems with both high‐security and superior electrochemical performance. Herein, in contrast to the conventionally used polymer/ceramic/polymer sandwich electrolyte, an efficient green and scalable powder‐polishing synthetic method is developed to fabricate a pyrolyzed‐polyacrylonitrile modified Na super ionic conductor (NASICON) electrolyte to relieve polarization of integrated composite SSE and ameliorate interfacial contact between the electrolyte and the Na anode. Furthermore, introducing S in the preferable isotropous sulfurized polyacrylonitrile (SPAN) interlayer can trigger dehydrogenation and cyclization of polyacrylonitrile with chemically‐bonded short‐chain SS segments, which can bond with Na+ to redistribute the interfacial electric field and homogenize transported Na+ flux, leading to transition of Na deposition behavior from dendrite growth mode to lateral flat‐shape growth tendency. The conjugated polymer backbones possess delocalized radicals that can activate formed short‐chain sulfides to reconnect to the backbones, thus maintaining superior structural stability. Benefiting from the rational interfacial design, a record‐high value of 1.4 mA cm−2 for critical current density of Na/SPAN‐NASICON/Na cells is obtained. Moreover, SPAN is used as a cathode to assemble solid‐state Na/SPAN‐NASICON/SPAN Na‐organosulfur batteries, demonstrating superior capacity and cycling‐stability. The rational SPAN‐based structural design strategy may provide an avenue for potential application of solid‐state alkali metal batteries.
