“…Separators in Na‐ion research often match standard material used in commercial Li‐ion cells, consisting of a polymer nanofiber matting such as polypyrrole or polyethylene, [189] which may be treated through grafting or irradiation to enhance ionic conductivity. [190] Alternative materials such as glass microfibre [191] are also supplied pre‐made for use as separators in battery research. As a result, Na‐ion battery researchers can select from a range of separator types, ready for use without further processing in the laboratory.…”

Before the viability of a cell formulation can be assessed for implementation in commercial sodium ion batteries, processes applied in cell production should be validated and optimized. This review summarizes the steps performed in constructing sodium ion (Na‐ion) cells at research scale, highlighting parameters and techniques that are likely to impact measured cycling performance. Consistent process‐structure‐performance links have been established for typical lithium‐ion (Li‐ion) cells, which can guide hypotheses to test in Na‐ion cells. Liquid electrolyte viscosity, sequence of mixing electrode slurries, rate of drying electrodes and cycling characteristics of formation were found critical to the reported capacity of laboratory cells. Based on the observed importance of processing to battery performance outcomes, the current focus on novel materials in Na‐ion research should be balanced with deeper investigation into mechanistic changes of cell components during and after production, to better inform future designs of these promising batteries.

“…18 The commonly used commercial separator for aqueous supercapacitors is polypropylene (PP) membranes, which have a large pore size, non-uniformity, no ion selectivity, and limited ionic conductivity in many electrolytes. 19–21 The development of AEESC separators with ion selectivity, minimal resistance to ion movement, greater safety and stability is urgently needed for next-generation devices with better safety and performance characteristics. Chen et al 5 described the specific SDC phenomenon of the hybrid capacitor based on the electrolyte containing a quinone/hydroquinone redox pair.…”

“…Presently, research on the latter topic is greatly focused on nanostructured materials [18,[24][25][26][27][28]. Among them, electrospun nanomaterials, suitable for production at the large-scale and able to meet requirements of a wide range of EES applications [18,27,28], have been extensively evaluated as active components in post-lithium batteries [18,[27][28][29][30][31].…”

Effect of Germanium Incorporation on the Electrochemical Performance of Electrospun Fe2O3 Nanofibers-Based Anodes in Sodium-Ion Batteries

et al. 2021

Fe2O3 and Fe2O3:Ge nanofibers (NFs) were prepared via electrospinning and thoroughly characterized via several techniques in order to investigate the effects produced by germanium incorporation in the nanostructure and crystalline phase of the oxide. The results indicate that reference Fe2O3 NFs consist of interconnected hematite grains, whereas in Fe2O3:Ge NFs, constituted by finer and elongated nanostructures developing mainly along their axis, an amorphous component coexists with the dominant α-Fe2O3 and γ-Fe2O3 phases. Ge4+ ions, mostly dispersed as dopant impurities, are accommodated in the tetrahedral sites of the maghemite lattice and probably in the defective hematite surface sites. When tested as anode active material for sodium ion batteries, Fe2O3:Ge NFs show good specific capacity (320 mAh g−1 at 50 mA g−1) and excellent rate capability (still delivering 140 mAh g−1 at 2 A g−1). This behavior derives from the synergistic combination of the nanostructured morphology, the electronic transport properties of the complex material, and the pseudo-capacitive nature of the charge storage mechanism.
