“…22 However, some materials with fluorite or tysonite type structure can achieve high ionic conductivities without a high defect concentration. 23,24 Geometric frustration from size mismatch of the cation lattice was recently also discussed to play an important role for the conductivity of multinary fluorides with fluorite type structure. 25 In general, only a few stable fluorides exhibit significant ionic conductivity, while being insulators for the transport of electrons due to a wide bandgap.…”

“…However, as shown in Figure 17A, capacity still faded though to a reduced extent. To further improve the battery performance, the authors changed the BiF 3 electrode with ball‐milled BiF 3 /C (80:20 wt% pulverized BiF 3 : acetylene black) to increase the conductivity and specific area of the electrode 43 . It also increased the first discharge/charge capacities to 427/239 mAh/g.…”

Summary Fluorine, as the most electronegative element, provides the highest electrode potential when it undergoes redox reactions. Moreover, fluoride ion is intrinsically an excellent charge carrier in both electrolytes and electrode structures owing to its small size, low atomic weight, and good ionic mobility. Hence, batteries based on fluorine electrochemistry, the so‐called fluoride ion batteries (FIBs), have recently been deemed as an alternative next‐generation high energy density battery system. This article reviews the recent progress in FIBs based on liquid electrolytes. The mechanisms, advantages, and drawbacks of FIBs are discussed. In the end, the perspective illuminating the research directions for further development is presented.

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...
