“…Further, coin cell based systems were proposed by Grenier et al, where a high temperature stable epoxy resin can be used for sealing, facilitating improved longer-term operability. 31 There also exist some reports 32,33 on FIBs, which are based on liquid electrolytes, which can then be investigated in the most common Swagelok-type setup. For instance, Davis et al reported 33 on standard three electrode systems for FIBs based on a liquid electrolyte.…”

“…Apart from some limited reports on primary batteries based on fluoride ions in the 1970s 11,12 , the first report on electrochemical rechargeable FIBs was proposed at 2011 by Fichtner et al 13 , based on an all-solid-state battery with La 0.9 Ba 0.1 F 2.9 as the solid electrolyte and conversion-based metal fluorides as active electrodes (e.g., CuF 2 , BiF 3 , and SnF 2 as the active cathode materials). Since then, the efforts on investigating such systems were further increased, addressing the development of solid [14][15][16][17][18] and liquid 19,20 electrolytes and improved cell designs 21,22 as well as the screening of conversion-based electrodes [23][24][25][26] .…”

Fluoride ion batteries (FIBs) are a recent alternative all-solid-state battery technology. However, the FIB systems proposed so far suffer from poor cycling performance. In this work, we report La 2 NiO 4.13 with a Ruddlesden-Popper type structure as an intercalation-based active cathode material in all solid-state FIB with excellent cycling performance. The critical charging conditions to maintain the conductivity of the cell were determined, which seems to be a major obstacle towards improving the cycling stability of FIBs. For optimized operating conditions, a cycle life of about 60 cycles and over 220 cycles for critical cutoff capacities of 50 mAh/g and 30 mAh/g, respectively, could be achieved, with average Coulombic efficiencies between 95-99%. Cycling of the cell is a result of fluorination/de-fluorination into and from the La 2 NiO 4+d cathode, and it is revealed that La 2 NiO 4.13 is a multivalent electrode material. Our findings suggest that La 2 NiO 4.13 is a promising high energy cathode for FIBs.

Solid solution of bismuth(III) fluoride (BiF 3 ) and barium(II) fluoride (BaF 2 ) with a variety of crystal structures was prepared, and their electrochemical performances were evaluated on a fluoride shuttle battery (FSB) system. BiF 3 -BaF 2 based solid solution (Bi 1-x Ba x F 3-x (x = 0) with orthorhombic phase, x = 0.2 with hexagonal phase, and x = 0.4 with cubic phase) were successfully obtained with the mechanical alloy method. The change from Bi 1-x Ba x F 3-x (x = 0) (orthorhombic) to x = 0.2 (hexagonal) improved the initial reversible capacity and the capacity retention during cycling. The change from x = 0.2 (hexagonal) to 0.4 (cubic) led to further improvement in capacity retention during cycling; however, the initial reversible capacity decreased due to the substitution of excess amount of barium that did not contribute to the redox reaction. For the BiF 3 -based compound, controlling the crystal structure and substitution of inactive element affected the FSB performance.Recently, a variety of secondary batteries have been developed. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] Our group selected and developed fluoride shuttle battery (FSB) with liquid-electrolyte. [18][19][20][21][22] The discharge (MF x + xe -! M + xF -; M: metal) and charge (M + xF -! MF x + xe -) reactions of metal fluoride (MF x ) electrode (e. g. bismuth(III) fluoride (BiF 3 )) on the FSB system was successful. [18][19][20][21][22] However, the FSB performance did not meet the requirement of the device; further performance improvement was required. It has been reported that compound with a variety of crystal structures and elemental composition can be used as active material for a secondary battery, and these factors greatly affected the electrochemical reaction mechanism and electrochemical performance. [23][24][25] Furthermore, the substitution of elements that did not participate in the redox reaction also affected the improvement of the battery performance, because it can contribute to the improvement of structure stability during the charge and discharge processes. [26][27][28] Bervas et al. reported that BiF 3 can be used as active material on lithium ion battery (LIB) system [29][30][31] and the battery performance of the BiF 3 electrode with orthorhombic and hexagonal phases were different. [29] There were some BiF 3 -based compounds with a variety of crystal structure such as orthorhombic, hexagonal, and cubic. [32][33][34] Previous report indicated that the barium can be substituted into BiF 3 and crystal structure of BiF 3 -BaF 2 solid solution was changed by the ratio of BiF 3 and BaF 2 . [32][33][34] Previously, we prepared the BiF 3 -BaF 2 solid solution with three types of crystal structures, and the effect of crystal structure on the electrochemical performance was evaluated on the LIB system. [35] The results indicated that the BiF 3 -BaF 2 compound with hexagonal phase showed higher electrochemical performance than those with orthorhombic and cubic phases. [35] We expected that a similar effect m...
