“…After 400 cycles, the capacity of PB-5 was still 97% of the initial capacity, while the capacity retention of PB-1 was 91%, which was also higher compared with other cathode materials for sodium-ion batteries. [4][5][6][7][8][9][10][11][12][13][14][15][16][17] This demonstrates that the reduction of the vacancies and coordinating water in the Na1+xFe[Fe(CN)6] framework results in structural stability of the PB compound, which gives rise to a higher capacity and greater cycling stability during the charge-discharge processes. The discharge-charge curves with cycles of the Na1+xFe[Fe(CN)6] cathode are plotted in Figure S6.…”

“…Hence, it is crucial to develop a non-toxic, low-cost, high-capacity, stable cathode material for SIBs to ensure large-scale and long-term applications. Up to now, transition metal (M) oxides (NaxMO2+y), [4][5][6][7][8] phosphates, 9-12 fluorides, 13 and hexacyanoferrates [14][15][16][17] have been reported as cathode materials for SIBs. Few materials, however, can have both high capacity (> 100 mAh g-1) and long cycle life simultaneously.…”

Chemistry of Materials, 27 (6), 1997Materials, 27 (6), -2003 Facile method to synthesize Na-enriched Na1+xFeFe(CN)6 frameworks as cathode with superior electrochemical performance for sodium-ion batteries AbstractDifferent Na-enriched Na 1+x FeFe(CN) 6 samples can be synthesized by a facile one-step method, utilizing Na 4 Fe(CN) 6 as the precursor in a different concentration of NaCl solution. As-prepared samples were characterized by a combination of synchrotron X-ray powder diffraction (S-XRD), Mössbauer spectroscopy, Raman spectroscopy, magnetic measurements, thermogravimetric analysis, X-ray photoelectron spectroscopy, and inductively coupled plasma analysis. The electrochemical results show that the Na 1.56 Fe[Fe(CN) 6 ]·3.1H 2 O (PB-5) sample shows a high specific capacity of more than 100 mAh g -1 and excellent capacity retention of 97% over 400 cycles. The details structural evolution during Na-ion insertion/ extraction processes were also investigated via in situ synchrotron XRD. Phase transition can be observed during the initial charge and discharge process. The simple synthesis method, superior cycling stability, and cost-effectiveness make the Na-enriched Na 1+x Fe[Fe(CN) 6 ] a promising cathode for sodium-ion batteries.Keywords method, batteries, facile, cathode, sodium, electrochemical, superior, frameworks, 6, cn, xfefe, na1, enriched, na, synthesize, ion, performance Disciplines Engineering | Physical Sciences and Mathematics Publication DetailsLi, W., Chou, S., Wang, J., Kang, Y., Wang, J., Liu, Y., Gu, Q., Liu, H. & Dou, S.

“…In recent years, various materials, such as manganese dioxide and Prussian blue analogues (PBA), have been reported as cathode materials for ARZIBs [16,17]. In particular, PBAs are notable potential cathode materials for application in ARZIBs owing to their superior characteristics, such as structural stability, large channels, and ease of synthesis [9,18]. Additionally, these materials have large open sites (4.6 Å in diameter) and <100> channels (3.2 Å in diameter), which enable the rapid diffusion of various hydrated metal ions, including zinc ions [19][20][21].…”

Abstract. In this study, a concentrated electrolyte was applied in an aqueous rechargeable zinc-ion battery system with a zinc hexacyanoferrate (ZnHCF) electrode to improve the electrochemical performance by changing the hydration number of the zinc ions. To optimize the active material, ZnHCF was synthesized using aqueous solutions of zinc nitrate with three different concentrations. The synthesized materials exhibited some differences in structure, crystallinity, and particle size, as observed by X-ray diffraction and scanning electron microscopy. Subsequently, these well-structured materials were applied in electrochemical tests. A more than two-fold improvement in the charge/discharge capacities was observed when the concentrated electrolyte was used instead of the dilute electrolyte. Additionally, the cycling performance observed in the concentrated electrolyte was superior to that in the dilute electrolyte. This improvement in the electrochemical performance may result from a decrease in the hydration number of the zinc ions in the concentrated electrolyte.

density. Therefore, developing highcapacity anode and cathode materials or new battery systems have drawn extensive attentions. [6,[21][22][23][24][25][26][27][28] Metal anodes, especially those with high-capacity and low-cost are promising alternative anode materials for LIBs in replace of graphite anode. [29][30][31][32][33][34] Generally, the metal anodes electrochemically alloy/ de-alloy with Li + to complete the battery reaction, which can store more energy than the intercalation/deintercalation mechanism in graphite. Table 1 displays the electrochemical properties of typical metallic anodes (Al, Sn, Zn, Mg, Sb, and Bi) with Li and graphite for comparison. While the graphite anodes suffer from low capacity (372 mA h g −1 ) and Li anodes suffer from severe safety issues caused by lithium dendrites, these metal anodes have many advantages in terms of high theoretical capacities, moderate operation potential for less dendrites formation, high abundance and low cost. [35] For example, aluminum has high theoretical capacity (993 mA h g −1 or 1411 mA h cm −3 for LiAl) with moderate potential plateau (≈0.38 V vs Li + /Li). [35,36] Considering both of the capacity increase and voltage drop by using metal anodes in a LIB model, Obrovac et al. calculated the volumetric energy increase in comparison to graphite based commercial battery (Table 1). [37] In such a model, the volumetric energy densities could be increased by different extents ranging from 10-42% when metal anodes were used. It is worth noticing that some recent studies have raised the idea of directly using metal foil as active anode material and simultaneously current collector. [38,39] This strategy can eliminate the usage of binder and conductive carbon black for anode preparation, simplify the battery processing steps, and also increase the loading amount of active materials, thus further enhancing the energy density and reducing the battery prices.While the metal anodes show good potential for application in high-performance LIBs, the main challenge for these metallic anodes is their large volume change caused by lithiation/delithiation process during cycling. [37,40,41] As the lithiation proceeds more deeply, the volume change becomes more severely for alloying anodes. For instance, the volume change of Sn (260%, Li 4.4 Sn) is larger than Al (97%, LiAl). The huge volume change could cause crack and pulverization of metal anodes, resulting in quick capacity decay and short cycling life. [42][43][44][45][46] Besides, metallic anode materials usually exhibited high first-cycle capacity loss due to their high reactivity withThe ever-growing market of portable electronic devices and electric vehicles has significantly stimulated research interests on new-generation rechargeable battery systems with high energy density, satisfying safety and low cost. With unique potentials to achieve high energy density and low cost, rechargeable batteries based on metal anodes are capable of storing more energy via an alloying/de-alloying process, in comparison to tradi...
