“…Owing to the chemically bonded high S contents and relative stable cycling stability of SPAN as well as excellent ionic transport performance of SPAN‐NASICON SSE, the integrated Na/SPAN‐NASICON/SPAN Na‐organosulfur full cell demonstrates superior RT galvanostatic performance of 357.1 mAh g −1 after 100 cycles (Figure 6f), which is competitive with the reported liquid‐state Na–S batteries. [ 54,55 ] This design further indicates that isotropous SPAN possesses huge potential for developing applicable solid‐state Na metal batteries. The overall performance may be further improved by adjusting the degree of polymerization and the content of S as well as heteroatomic doping strategies and so on, which needs to be explored in the later research.…”

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.

“…Nonaqueous Na‐S and K‐S batteries also work under a similar mechanism as that for the Li–S battery. [ 58 ] Electrolytes of Na‐S and K‐S batteries are formulated by following the same idea of Li–S system, being prepared by dissolving either a sodium salt [ 59 ] or a potassium salt [ 60 ] in a single ether‐based solvent or a mixed solvent of ethers. The charge‐discharge of Na‐S and K‐S cells also involves the formation of polysulfide intermediates that are soluble in either‐based solvents.…”

Nonaqueous conversion-reaction sulfur chemistry has been attracting increasing attention over the past decade for the development of nextgeneration lithium-based batteries. Li-S batteries are currently approaching a nexus stage from lab-scale experiments to possible pragmatic applications. Inspired by the success of Li-S chemistry, other metal-sulfur batteries with a variety of metallic anodes, such as sodium, potassium, magnesium, calcium, and aluminum, have also started to attract attention. In comparison to lithium, Na, Mg, Al, K, and Ca are naturally more abundant and affordable.

“…Sulfur is used as cathode material in fabricating Na-S batteries owing to its sufficiently high natural abundance, low cost and non-toxic nature. In addition, sulfur offers high theoretical energy density of 1230 Wh kg −1 and theoretical discharge capacity of 1672 mAh g −1 with respect to the electrochemical reaction 2Na + S → Na 2 S. [11][12][13] Therefore, S poses as an exceptional candidate as cathode for the accommodation of Na ions, which has relatively higher weight as compared to Li, in Na-S batteries. The Na-S batteries may be classified into high temperature and room temperature Na-S batteries.…”

The research interests on sodium-sulfur (Na-S) batteries which have regained the worldwide attention from last few years. Na-S battery technology seems a good choice for future grid level stationary energy storage units where the cost is as important as the performance from practical applications point of view. This paper summarizes basic principle of operation, major benefits, and challenges of room temperature Na-S batteries using composite sulfur based cathodes. Few recent techniques employed by the research groups to develop composite sulfur cathodes for Na-S batteries are highlighted including the guidelines for upcoming Na-S batteries.
