Journal of Power Sources 557 2023年2月

Ba0.6La0.4F2.4 (BLF) is one of the promising candidates for solid-state electrolytes in fluoride-ion batteries owing to the wide electrochemical potential window. Compared with a BLF single crystal, the microstructure-modified BLF polycrystals by ...

Among the three inequivalent fluorides in tysonite CeF3(F1, F2, and F3 in the ratio of 12:4:2 per unit cell), we show by 19F solid-state NMR that F1 is solely responsible for the ion conductivity in Ce1-xSrxF3-x(x = 0.001) at 0 °C. It is further s...

¹⁹F NMR studies on ionic conduction pathways in tysonite-CeF<inf>3</inf>

Miwa Murakami Atsushi Mineshige

Journal of Physics and Chemistry of Solids 161 2022年2月

There has been a long-standing controversy over ion conducting pathways in tysonite. To unravel the pathways in CeF3, high-resolution MAS NMR spectra of 19F in CeF3 at −40–240 °C are analyzed on the bases of the calculated dipolar coupling tensor ...

Electrochemical Impedance Spectroscopy Part 1: Fundamentals^†

Kingo Ariyoshi Zyun Siroma Atsushi Mineshige Mitsuhiro Takeno Tomokazu Fukutsuka Takeshi Abe Satoshi Uchida

Electrochemistry 90(10) 2022年

Electrochemical impedance spectroscopy (EIS) enables the examination of the electrochemical nature of electrodes and electrochemical cells by applying an alternating voltage (or current) and measuring the resulting current (or voltage). The resist...

Electrochemical Impedance Spectroscopy Part 2: Applications^†

Kingo Ariyoshi Atsushi Mineshige Mitsuhiro Takeno Tomokazu Fukutsuka Takeshi Abe Satoshi Uchida Zyun Siroma

Electrochemistry 90(10) 2022年

Electrochemical impedance spectroscopy (EIS) is widely used for the analysis of various electrochemical devices, as it can quantitatively evaluate the main kinetic parameters related to electrochemical phenomena by analysis using equivalent circui...
