“…Recent years have seen increasing concerns about potential corrosion problems related to chloride-containing electrolytes. Oh and colleagues 66 have reported that PY14Cl is an effective inhibitor against the corrosion by Cl – at high potentials. Therefore, PY14 + is not only a pillar for expanding TiS 2 but also a corrosion inhibitive additive.…”

Magnesium rechargeable batteries potentially offer high-energy density, safety, and low cost due to the ability to employ divalent, dendrite-free, and earth-abundant magnesium metal anode. Despite recent progress, further development remains stagnated mainly due to the sluggish scission of magnesium-chloride bond and slow diffusion of divalent magnesium cations in cathodes. Here we report a battery chemistry that utilizes magnesium monochloride cations in expanded titanium disulfide. Combined theoretical modeling, spectroscopic analysis, and electrochemical study reveal fast diffusion kinetics of magnesium monochloride cations without scission of magnesium-chloride bond. The battery demonstrates the reversible intercalation of 1 and 1.7 magnesium monochloride cations per titanium at 25 and 60 °C, respectively, corresponding to up to 400 mAh g−1 capacity based on the mass of titanium disulfide. The large capacity accompanies with excellent rate and cycling performances even at room temperature, opening up possibilities for a variety of effective intercalation hosts for multivalent-ion batteries.

Rechargeable batteries are considered one of the most effective energy storage technologies to bridge the production and consumption of renewable energy. The further development of rechargeable batteries with characteristics such as high energy density, low cost, safety, and a long cycle life is required to meet the ever‐increasing energy‐storage demands. This Review highlights the progress achieved with halide‐based materials in rechargeable batteries, including the use of halide electrodes, bulk and/or surface halogen‐doping of electrodes, electrolyte design, and additives that enable fast ion shuttling and stable electrode/electrolyte interfaces, as well as realization of new battery chemistry. Battery chemistry based on monovalent cation, multivalent cation, anion, and dual‐ion transfer is covered. This Review aims to promote the understanding of halide‐based materials to stimulate further research and development in the area of high‐performance rechargeable batteries. It also offers a perspective on the exploration of new materials and systems for electrochemical energy storage.

“…First, clumsy Mg 2+ intercalation is the primary limitation for the choice of competent cathode materials, because the strong Coulombic interactions between the divalent Mg 2+ ions and the anions in the host materials often result in sluggish diffusion kinetics and slow interfacial charge transfer . Second, to design appropriate electrolytes for Mg plating/stripping with high Coulombic efficiency, wide electrochemical window, and good compatibility with the cathodic materials is another great challenge .

3833 mAh cm −3 nearly double that of lithium (2062 mAh cm −3 ), and exhibits a relatively negative reduction potential of −2.4 V versus standard hydrogen electrode (SHE). [6][7][8][9] Despite of these intriguing merits, the practical employment of RMBs is hampered by several main hurdles. First, clumsy Mg 2+ intercalation is the primary limitation for the choice of competent cathode materials, because the strong Coulombic interactions between the divalent Mg 2+ ions and the anions in the host materials often result in sluggish diffusion kinetics and slow interfacial charge transfer. [10][11][12][13] Second, to design appropriate electrolytes for Mg plating/ stripping with high Coulombic efficiency, wide electrochemical window, and good compatibility with the cathodic materials is another great challenge. [14,15] Therefore, to develop advanced cathode materials capable of rapid Mg 2+ insertion/extraction in suitable electrolytes for reversible Mg plating/stripping is highly desirable. Since the pioneering work of Chevrel phase compounds (Mo 6 S 8 ) reported by Aurbach et al. in 2000, [16] tremendous efforts have been devoted to develop cathode materials for RMBs, including transition metal oxides (MnO 2 , V 2 O 5 , Mn 3 O 4 , WO 3 , Co 3 O 4 ), [17-21] polyanionic compounds (Mg 1.03 Mn 0.97 SiO 4 , MgCoSiO 4 ), [22,23] and transition metal dichalcogenides (TMDs, such as TiS 2 , MoS 2 , WSe 2 ). [24][25][26][27][28] However, most oxides and polyanionic compounds suffer from low capacity and poor cycling performance owing to the strong interactions between divalent Mg 2+ and O 2− in the hosts. [25,29] On the contrary, TMDs are deemed to be a class of promising cathode materials with more favorable kinetics, attributing to the relatively weaker MgS or MgSe bonds than MgO bond. [25,28,30] Nevertheless, layered TMDs also suffer from slow Mg 2+ ion diffusion due to the narrow interlayer spacing and the high polarity of Mg 2+ . [31] Recently, it was reported that the interlayer distances of TMDs could be expanded by intercalating guest molecules (water or organic molecules), enlarging the dimension of ion diffusion channels and shielding the Coulombic interactions between Mg 2+ and the lattice anions of hosts. 13,27 In addition, the intercalated molecules served as interlayer pillars are conducive to maintain the framework of host materials for prolonged cycles. [32,33] Rechargeable magnesium batteries (RMBs) are attractive candidates for large-scale energy storage owing to the high theoretical specific capacity, rich earth abundance, and good safety characteristics. However, the development of desirable cathode materials for RMBs is constrained by the high polarity and slow intercalation kinetics of Mg 2+ ions. Herein, it is demonstrated that 2-ethylhexylamine pillared vanadium disulfide nanoflowers (expanded VS 2 ) with enlarged interlayer distances exhibit greatly boosted electrochemical performance as a cathode material in RMBs. Through a one-step solution-phase synthesis and in situ 2-ethylhexylamine intercalatio...
