“…7 A handful of studies have instead focused on using anions as the active species. 8,9 Amongst the various candidates for active anion batteries, fluoride (F -) is especially attractive due to its earth-abundance, light weight, high electronegativity, and reasonably fast diffusion in liquid or solid electrolytes. [10][11][12][13][14][15][16][17] In contrast to the success of Li batteries using two intercalation electrodes, most research on fluoride-ion batteries (FiBs) has followed a different path involving conversion reactions, 18,19 pairing metals with metal fluorides, such as: 11 3Sn + 2BiF3 → 3SnF2 + 2Bi.…”

Chloride ion batteries (CIBs) are a promising type of energy storage device due to their high theoretical volumetric energy density and abundant reserves of chlorine-containing precursors. However, the unsatisfactory cycling performance and structural instability of cathode materials hinder their practical application. In this work, layered double hydroxides (LDHs), which consist of a trimetallic NiVAl hydroxide host matrix and interlayer Cl − , are demonstrated to be high-performance cathode materials for CIBs. The Ni 2 V 0.9 Al 0.1 -Cl LDH is capable of delivering a high initial capacity of 312.2 mAh g −1 at 200 mA g −1 and an ultralong life over 1000 cycles (with a capacity higher than 113.8 mAh g −1 ). Such a long cycling life exceeds that of any reported CIBs. The remarkable Cl − -storage performance of the Ni 2 V 0.9 Al 0.1 -Cl LDH is ascribed to the synergetic contributions from V m+ (high redox activity), Ni 2+ (favorable electronic structure), and inactive Al 3+ (enhances the structural stability), which is revealed by a comprehensive study that utilizes synchrotron X-ray absorption near-edge structure experiments, kinetic investigations, and theoretical calculations. This study provides an effective strategy to achieve superior rechargeable batteries, which are applicable to large-scale energy storage and power grids.room-temperature chloride ion batteries (CIBs) based on Cl − shuttling [6][7][8][9][10] have attracted intensive attention as a result of their large theoretical volumetric energy density (up to 2500 Wh L −1 ). [11] In addition, the abundance of chloride-containing materials and their availability worldwide not only lower the costs but also enable manufacturing all over the world. Another key advantage of CIBs is their dendritefree feature, which is derived from the simple migration of Cl − , making CIB systems more secure and suitable for large-scale energy storage. [12] Since the first proof that the reversible shuttle of chloride ions between a metal chloride cathode (BiCl 2 , CoCl 2 , and VCl 3 ) and a lithium anode was proposed by Zhao et al., [5] metal oxychlorides [6,13] and chloride-doped organic polymers, [14,15] such as PPy and PANI, have been subsequently demonstrated as possible electrode materials in CIBs. Although some progress has been made in CIB cathode materials during the past few years, it is still at the initial stage compared with the development of metal-ion batteries. One urgent issue to be solved is their short cycling life; i.e., most of these cathode materials can only sustain dozens of charge/discharge cycles with a moderate capacity of ≈40−100 mAh g −1 . Therefore, exploiting suitable Cl − -hosting cathode materials with a simultaneous high capacity and long cycling life is a top priority for the development of rechargeable CIBs.Layered double hydroxides (LDHs), whose structure can be generally expressed by the formula [M II 1−x M III x (OH) 2 ] (A n− ) x/n ·mH 2 O (M II and M III are divalent and trivalent metals respectively, and A n− is an interlayer anion co...

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...
