“…This topic has been extensively explored for lithium batteries. [ 189 ] In SIBs, several polymers have been investigated for the realization of GPEs, including polyethylene oxide (PEO), [ 190–193 ] perfluorinated sulfonic membranes (NAFION type), [ 194–196 ] polyacrylonitrile (PAN), [ 197,198 ] poly(methyl methacrylate) (PMMA), [ 199–201 ] and polyvinylidene fluoride (PVDF). [ 202–210 ] The mixture of PEO with short‐chain length glyme leads to a homogeneous gel polymer electrolyte with highly isotropic properties.…”

technologies. Unlike lithium, whose market is already very tight, sodium mineral deposits are almost infinite, evenly distributed worldwide, much easier to extract and thereby attainable at low cost. [1][2][3][4] If the realization of Na-rechargeable batteries could be practically possible, there will be nearly three orders of magnitude relaxation in the constraints on lithium-based resources, accompanied by sustainability, improved environmental benevolence, and cost reduction ( Table 1). Even more appealing is the possible use of the widely available and lighter aluminum, rather than copper, as negative current collector and hard carbon from renewable sources instead of graphite for the negative electrode. Finally, the stability of sodium-ion batteries (SIBs) in the fully discharged state would significantly enhance the safety associated with the shipment of large-format SIBs worldwide.These beneficial features of sodiumbased cells revived the research work on Na-based rechargeable batteries and accordingly captured the attention of both the academic research and industry sectors. However, similar to LIB, most of the research work in Na-based batteries have focused on the development and elaboration of negative and positive For sodium (Na)-rechargeable batteries to compete, and go beyond the currently prevailing Li-ion technologies, mastering the chemistry and accompanying phenomena is of supreme importance. Among the crucial components of the battery system, the electrolyte, which bridges the highly polarized positive and negative electrode materials, is arguably the most critical and indispensable of all. The electrolyte dictates the interfacial chemistry of the battery and the overall performance, having an influence over the practical capacity, rate capability (power), chemical/thermal stress (safety), and lifetime. In-depth knowledge of electrolyte properties provides invaluable information to improve the design, assembly, and operation of the battery. Thus, the full-scale appraisal of both tailored electrolytes and the concomitant interphases generated at the electrodes need to be prioritized. The deployment of large-format Na-based rechargeable batteries also necessitates systematic evaluation and detailed appraisal of the safety-related hazards of Na-based batteries. Hence, this review presents a comprehensive account of the progress, status, and prospect of various Na + -ion electrolytes, including solvents, salts and additives, their interphases and potential hazards.

Owing to the promise of high safety and energy density, all‐solid‐state batteries are attracting incremental interest as one of the most promising next‐generation energy storage systems. However, their widespread applications are inhibited by many technical challenges, including low‐conductivity electrolytes, dendrite growth, and poor cycle/rate properties. Particularly, the interfacial dynamics between the solid electrolyte and the electrode is considered as a crucial factor in determining solid‐state battery performance. In recent years, intensive research efforts have been devoted to understanding the interfacial behavior and strategies to overcome these challenges for all‐solid‐state batteries. Here, the interfacial principle and engineering in a variety of solid‐state batteries, including solid‐state lithium/sodium batteries and emerging batteries (lithium–sulfur, lithium–air, etc.), are discussed. Specific attention is paid to interface physics (contact and wettability) and interface chemistry (passivation layer, ionic transport, dendrite growth), as well as the strategies to address the above concerns. The purpose here is to outline the current interface issues and challenges, allowing for target‐oriented research for solid‐state electrochemical energy storage. Current trends and future perspectives in interfacial engineering are also presented.

“…Typically, polymer electrolyte is prepared by dissolving a Na salt, such as sodium perchlorate (NaClO 4 ), sodium bis(trifluoromethanesulfonyl) imide (NaTFSI), or sodium hexafluorophosphate (NaPF 6 ) in a polymer host, including polyethylene oxide (PEO), [ 20–22 ] poly(vinylidene fluoride‐ co ‐hexafluoropropylene) (PVDF–HFP), [ 23,24 ] poly(methyl methacrylate), [ 25,26 ] and polyacrylonitrile. [ 27,28 ] Owing to the excellent chemical stability and high solubility to Na salts, PEO‐based electrolyte is considered to be the most promising electrolyte material. [ 12,22 ] However, PEO‐based electrolyte appears limited mechanical properties, low oxidation potential, narrow voltage window (<4.0 V), and poor room‐temperature ionic conductivity (≈10 −6 S cm −1 ), which significantly limit their practical application for high‐performance SMBs.…”

Solid‐state sodium metal batteries (SMBs) are highly promising rechargeable batteries owing to the abundance and cost effectiveness of sodium. However, the low room‐temperature ionic conductivity and narrow voltage window of solid‐state electrolytes seriously inhibit the development of SMBs. Herein, an ethoxylated trimethylolpropane triacrylate based quasisolid‐state electrolyte (ETPTA–NaClO4–QSSE) is developed by photopolymerization for high‐energy‐density solid‐state SMBs. The ETPTA–NaClO4–QSSE exhibits remarkable room‐temperature ionic conductivity of 1.2 mS cm−1, a wide electrochemical window of >4.7 V versus Na+/Na, and excellent flexibility. Owing to outstanding interfacial compatibility between this electrolyte and the electrode, Na metal symmetrical batteries show ultralong cyclability with 1000 h at 0.1 mA cm−2, and ultralow overpotential of 355 mV at 1 mA cm−2, indicative of significant suppression of the Na dendrite growth. Notably, Na3V2(PO4)3 (NVP) full batteries (NVP||ETPTA–NaClO4–QSSE||Na) display unprecedented rate capability, with a recorded capacity of 55 mAh g−1 at 15 C, higher than any achieved so far in solid‐state SMBs, and long‐term cycling stability at 5 C, offering a capacity retention of 97% after 1000 cycles. Furthermore, NVP||ETPTA–NaClO4–QSSE||Na pouch cells represent excellent flexibility and exceptional safety, demonstrative of wide applicability. Therefore, this work will open new opportunities to develop room‐temperature high‐energy‐density solid‐state SMBs.
