“…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.

“…A new positive electrode material with large capacity is needed for these devices, because current positive electrode materials utilize insertion reactions with intrinsically limited capacities based on one-(or less) electron reaction per formula unit (140 mAh g −1 for LiCoO 2 (0.5 Li) [4,5] and 170 mAh g −1 for LiFePO 4 (1 Li) [6]). Thus, instead of such insertion materials, iron(III) fluoride (FeF 3 ) has been receiving attention as a positive electrode material with a high theoretical capacity of 712 mAh g −1 based on the three-electron reaction, reasonably high average operating potential of 2.7 V vs. Li + /Li, in addition to abundant resources of iron [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26].…”

Iron(III) fluoride (FeF 3 ) with low crystallinity and high surface area has been synthesized by a fluorolysis method, and applied as a positive electrode material for lithium secondary batteries. The FeF 3 prepared with a high molar ratio of hydrogen fluoride exhibits a high surface area and crystallinity. The FeF 3 sample treated at 300 °C under a F 2 /Ar atmosphere exhibits the highest surface area and was selected for further electrochemical test in view of improvement of performance in the potential region of conversion reactions. The initial discharge (lithiation) capacity was 676 mAh g −1 that was close to the theoretical capacity of FeF 3 (712 mAh g −1 ).Compared to the highly crystalline FeF 3 commercially available, the synthesized FeF 3 in the present study exhibited a low discharge capacity attributed to the insertion reaction because of the low crystallinity, and showed a low overpotential and larger capacity corresponding to the conversion reaction owing to the higher surface area of the fluorides.

“…S odium-ion rechargeable batteries, using abundant sodium sources, are suitable for use in distributed power systems that store renewable energy at individual houses [1][2][3][4] . Currently, sodium − sulphur (NAS) batteries 5 are used for large-scale storage, because they have high energy densities of up to 760 Wh kg − 1 .…”

Superionic glass-ceramic electrolytes for room-temperature rechargeable sodium batteries

Innovative rechargeable batteries that can effectively store renewable energy, such as solar and wind power, urgently need to be developed to reduce greenhouse gas emissions. All-solid-state batteries with inorganic solid electrolytes and electrodes are promising power sources for a wide range of applications because of their safety, long-cycle lives and versatile geometries. Rechargeable sodium batteries are more suitable than lithium-ion batteries, because they use abundant and ubiquitous sodium sources. solid electrolytes are critical for realizing allsolid-state sodium batteries. Here we show that stabilization of a high-temperature phase by crystallization from the glassy state dramatically enhances the na + ion conductivity. An ambient temperature conductivity of over 10 − 4 s cm − 1 was obtained in a glass-ceramic electrolyte, in which a cubic na 3 Ps 4 crystal with superionic conductivity was first realized. All-solid-state sodium batteries, with a powder-compressed na 3 Ps 4 electrolyte, functioned as a rechargeable battery at room temperature.
