“…[76][77][78] Likewise, magneto-ionic effects in Li-based conversion kind of electrodes are also reported. 79 R-HEOs and S-HEOs, are known to be tolerant to reversible lithiation and delithiation, while layered HEOs are can reversibly accommodate both Li and Na. 26,27,31,32,75 Thus, stable reversible control of magnetism via the electrochemically-driven insertion/extraction of ions might be feasible.…”

“…(B) In situ magnetic monitoring on a FeF 2 LIB as a function of the cyclic voltammetry scanning for the first three cycles at a scan rate of 0.25 mV s −1 over the potential window of 1.0-4.0 V at an applied magnetic field of 3 T. Schematics of the spin-polarized density of states at the surface of transition metal grains (C) before and (D) after discharge charge process originated from the reduction of FeF 3 because the current was negative at the beginning of the positive scanning (a similar phenomenon can also be found in the present FeF 2 LIBs, as shown in Figure 2B). 30 To clarify the controversy, we employed in situ magnetometry accompanying with the galvanostatic charge-discharge tests to detect the magnetization variation of FeF 2 LIBs upon cycling. As shown in Figure S3, the magnetic responses curves are consistent with the results in Figure 2B, demonstrating that the magnetization increase originates from the spin-polarized surface capacitance instead of the electrode reduction reaction.…”

“…3 The iron-based fluorides and oxo-fluorides are regarded as propitious candidates for conversion cathodes due to their high capacity, moderately high potential, and very low cost of iron. 4,5 The properties and crystal structures of various solid transition-metal oxo-fluorides with different structural characteristics have been reported. 6,7 However, the structures of the molecular species that can form these solids were barely investigated until recently when the molecules were readily prepared through reactions of laser-ablated transition-metal atoms with OF 2 in a cryogenic argon matrix.…”

“…The transition metals (TMs; M in chemical formulas) are elements with a particularly rich chemistry owing to the stepwise occupation of the d-valence shell, wide range of oxidation states (OSs), and variety of valences. , TM oxides, fluorides, and oxo-fluorides have recently attracted additional interest due to the possibly increasing electric cell-level energy density that offers a pathway toward lower-cost Li-ion batteries . The iron-based fluorides and oxo-fluorides are regarded as propitious candidates for conversion cathodes due to their high capacity, moderately high potential, and very low cost of iron. , The properties and crystal structures of various solid transition-metal oxo-fluorides with different structural characteristics have been reported. , However, the structures of the molecular species that can form these solids were barely investigated until recently when the molecules were readily prepared through reactions of laser-ablated transition-metal atoms with OF 2 in a cryogenic argon matrix. Many MO n species have been described in the literature, and a list of citations is provided in the Supporting Information, § S12.…”
