“…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.…”

Dou, S. (2015). Facile method to synthesize Na-enriched Na 1+x FeFe(CN) 6 frameworks as cathode with superior electrochemical performance for sodium-ion batteries. 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.

“…26 On the basis of elemental analysis by ICP-AES for Mn and Fe, AAS for Na, and TGA for water content, the NMHCF molecular formula was determined as Na 1.24 Mn[Fe(CN) 6 ] 0.81 ·1.28H 2 O. Although the crystal water content in the sample depends on the temperature and humidity, 21 the theoretical capacity of this hydrate can be roughly estimated as 120 mAh g ¹1 on the basis of 1.24 Na + extraction/ insertion.

From the viewpoint of the cost and safety, aqueous sodium-ion batteries are attractive candidate for large-scale energy storage. Although the operating voltage range of the aqueous battery is theoretically limited to 1.23 V by the electrochemical decomposition of water, the voltage restriction is a little bit eased in real aqueous battery system by the charge/discharge overvoltage. Effect of the concentrated electrolyte on the operation voltage was studied in aqueous Na-ion battery with Na 2 MnFe(CN) 6 hexacyanoferrates cathode and NaTi 2 (PO 4 ) 3 NASICON-type anode, in order to increase the discharge voltage. According to the cyclic voltammetry, the electrochemical window of diluted 1 mol kg −1 NaClO 4 aqueous electrolyte is only 1.9 V, whereas the corresponding electrochemical window of concentrated 17 mol kg −1 NaClO 4 aqueous electrolyte is widen to 2.8 V. This wide electrochemical window of the concentrated aqueous electrolyte allows the Na 2 MnFe(CN) 6 //NaTi 2 (PO 4 ) 3 aqueous sodium-ion system to work reversibly. By contrast, the framework of Na 2 MnFe(CN) 6 cathode was destroyed by the hydroxide anion generated in diluted 1 mol kg −1 electrolyte.

New types of energy storage are needed in conjunction with the deployment of renewable energy sources and their integration with the electrical grid. We have recently introduced a family of cathodes involving the reversible insertion of cations into materials with the Prussian Blue open-framework crystal structure. Here we report a newly developed manganese hexacyanomanganate open-framework anode that has the same crystal structure. By combining it with the previously reported copper hexacyanoferrate cathode we demonstrate a safe, fast, inexpensive, long-cycle life aqueous electrolyte battery, which involves the insertion of sodium ions. This high rate, high efficiency cell shows a 96.7% round trip energy efficiency when cycled at a 5C rate and an 84.2% energy efficiency at a 50C rate. There is no measurable capacity loss after 1,000 deep-discharge cycles. Bulk quantities of the electrode materials can be produced by a room temperature chemical synthesis from earth-abundant precursors.
