     概要を見る

    Deposition and dissolution of lithium metal have been investigated in an equimolar mixture of lithium bis(trifluoromethylsulfonyl)amide (LiTFSA) and glyme [triglyme (G3) or tetraglyme (G4)] solvate ionic liquid. The limiting current for deposition of lithiumwas not observed probably because of the high concentration of lithium species and a decrease in the local viscosity by the liberation of glyme. On the other hand, the dissolution of lithium was limited due to an increase in the local viscosity by the formation of [Li(TFSA)2]–. The formation of solid electrolyte interphase (SEI) was suggested to form by the cathodic decomposition of the solvate ionic liquids by electrochemical quartz crystal microbalance. Lithium phosphorous oxynitride (LiPON) thin film was found to act as the artificial SEI, which prevented the cathodic decomposition of the solvate ionic liquids and enabled the deposition and dissolution of lithium. The cycle performance of deposition and dissolution of lithiumwas found to be improved by coating a Cu substratewith vapor-grown carbon fiber.

  • Redox Reactions of Ag(I)/Ag and Ferrocenium/Ferrocene in 1-Butyl-1-methylpyrrolidinium Bis(fluorosulfonyl)amide Ionic Liquid

    Kato S., Serizawa N., Katayama Y.

    Journal of the Electrochemical Society (Journal of the Electrochemical Society)  170 ( 4 )  2023年04月

    ISSN  00134651

     概要を見る

    The electrode reactions of Ag(I)/Ag and ferrocenium/ferrocene (Fc+/Fc) were investigated in an ionic liquid, 1-butyl-1-methylpyrrolidinium bis(fluorosulfonyl)amide (BMPFSA). The potential of Ag(I)/Ag depended on the logarithm of the concentration of Ag(I), as predicted by the Nernst equation, indicating the Ag(I)/Ag can be used as a reference electrode reaction in BMPFSA. The reversible electrode reaction of Fc+/Fc was observed in BMPFSA by cyclic voltammetry. The donor number of BMPFSA was estimated to be 13 from the difference in the formal potentials of Ag(I)/Ag and Fc+/Fc, indicating the coordination ability of FSA- was slightly stronger than that of bis(trifluoromethylsulfonyl)amide (TFSA-). The diffusion coefficients (D) of Fc and Fc+ were (5.7 ± 0.7) and (3.3 ± 0.2) × 10-7 cm2 s-1, respectively. The ratio of D of Fc+ against that of Fc was smaller than those in TFSA--type ionic liquids, reflecting the higher charge density of FSA-. The standard rate constant (k 0) of Fc+/Fc was estimated to be (5.4 ± 1.1) × 10-3 cm s-1. The apparent activation energy for k 0 was close to the activation energy for D, suggesting the electrode reaction of Fc+/Fc can be regarded as the outer sphere electron transfer reaction with a very small reorganization energy.

  • Solid-Electrolyte Interphase Formation in Amide-Type Ionic Liquids in the Presence of Different Metal Cations

    Kato S., Serizawa N., Katayama Y.

    Journal of the Electrochemical Society (Journal of the Electrochemical Society)  170 ( 5 )  2023年

    ISSN  00134651

     概要を見る

    The formation of solid-electrolyte interphase (SEI) on a glassy carbon (GC) electrode in 1-butyl-1-methylpyrrolidinium bis(fluorosulfonyl)amide (BMPFSA) and 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)amide (BMPTFSA) containing Li+, Na+, K+, and Ni2+ was investigated using the redox reaction of ferrocene (Fc). The anodic peak potential (E pa) for the oxidation of Fc changed after holding the electrode at -1.4 to -1.5 V vs Ag|Ag(I) in BMPFSA in the presence of the alkali metal ions. The decomposition of FSA- was confirmed by X-ray photoelectron spectroscopy (XPS) on a GC electrode held at -1.5 V vs Ag|Ag(I) for 6 h in BMPFSA containing the alkali metal ions. The change in E pa may also suggest the formation of homogeneous SEI in the FSA--type ionic liquid. Moreover, E pa changed after holding the electrode at the potential more negative than -0.9 V vs Ag|Ag(I) in 50 mM Ni(TFSA)2/BMPTFSA while the decomposition of TFSA- was not confirmed by XPS on the electrode held at -1.1 V vs Ag|Ag(I) for 6 h, suggesting the bonds except C-F (e.g., S-C) were dissociated to form the SEI. Since the deposition potential of Ni in BMPTFSA was more negative than the SEI formation potential, the deposition of Ni may be inhibited by the SEI.

  • Electrochemical Behavior of Silver Halogenocomplexes in an Amide-Type Ionic Liquid

     概要を見る

    The electrode reactions of haloargentates were investigated in an aprotic and hydrophobic amide-type ionic liquid, 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)amide (BMPTFSA) in the presence of the halide ions. Silver halides, AgX (X- = Cl-, Br-, and I-) were found to be soluble in BMPTFSA containing 0.5 M BMPX to form halogenocomplex, [AgX3]2-. The cathodic reduction of [AgX3]2- to metallic Ag was observed within the electrochemical potential window of the ionic liquid, while the reduction potential was lower than that in the ionic liquid in the absence of X-. The equilibrium potentials of [AgX3]2-/Ag were in the order of [AgCl3]2- > [AgBr3]2- > [AgI3]2-, probably reflecting the thermodynamic stability of the complexes. The diffusion coefficients of [AgCl3]2-, [AgBr3]2-, and [AgI3]2- were 2.5, 2.0, and 1.6 × 10-7 cm2 s-1, respectively. The morphology of deposits strongly depended on the reduction potential. The nucleation and growth mechanism of Ag deposition was considered to be progressive rather than instantaneous. Formation of Ag nanoparticles dispersed in the ionic liquids was confirmed after potentiostatic cathodic reduction at -2.5 V vs Ag|Ag(I) using a transmission electron microscope.

  • Communication - Determination of the Formation Potential of Solid-Electrolyte Interphase in Amide-Type Ionic Liquids Containing Lithium Salts

    Kato S., Serizawa N., Katayama Y.

    Journal of the Electrochemical Society (Journal of the Electrochemical Society)  169 ( 7 )  2022年07月

    ISSN  00134651

     概要を見る

    The formation potentials of solid-electrolyte interphase (SEI) were investigated in 1-butyl-1-methylpyrrolidinium bis(fluorosulfonyl)amide (BMPFSA) and 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)amide (BMPTFSA) containing LiFSA and LiTFSA, respectively, by monitoring the redox reaction of ferrocene with high sensitivity. The SEI was found to affect the electrode kinetics of the outersphere electron transfer reaction. The SEIs with the thickness of less than a few nm formed in LiFSA/BMPFSA and LiTFSA/BMPTFSA at 2.4 and 2.5 V vs Li|Li(I), respectively. The cathodic decomposition of FSA- and TFSA- was considered to be promoted by the interaction with Li+ based on the ab-initio calculation.

  • Potential Dependence of the Impedance of Solid Electrolyte Interphase in Some Electrolytes

    Furuya R., Serizawa N., Katayama Y.

    Electrochemistry (Electrochemistry)  90 ( 5 )  2022年

    ISSN  13443542

     概要を見る

    The dependence of the impedances of lithium phosphorous oxynitride (LiPON) thin film and solid electrolyte interphase (SEI) formed by decomposition of some electrolytes on the electrode potential was investigated by electrochemical impedance spectroscopy. A LiPON thin film was prepared on a Ni electrode by radio frequency magnetron sputtering of Li3PO4 under nitrogen atmosphere. The resistance of the LiPON thin film decreased with lowering the electrode potential in an ionic liquid, 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl) amide (BMPTFSA) containing 1M LiTFSA. The similar potential dependence of the impedance of the SEI formed in 1M LiTFSA/BMPTFSA was observed, suggesting that the Li+ carrier density in the LiPON thin film and SEI increased with lowering the electrode potential probably due to the doping of Li+ from the electrolyte into the thin Li+ conductors in order to compensate the negative charge on the electrode. On the other hand, the potential dependence of the SEI formed in LiTFSA-tetraglyme (G4) solvate ionic liquid was insignificant because of the high concentration of Li+ in the SEI and electrolyte. The resistance of the SEI formed in 1M LiClO4/EC (ethylene carbonate) + DMC (dimethyl carbonate) (1 : 1 vol%) did not depend on the electrode potential, suggesting the thin and highly Li+ conductive SEI is formed in the organic electrolyte.
