New solid electrolytes are crucial for the development of all-solid-state lithium batteries with advantages in safety and energy densities over current liquid electrolyte systems. While some best solid-state Li+-ion conductors based on sulfides, their air sensitivity makes them less commercially attractive, attention is refocusing air-stable oxide-based Among these, LISICON-structured systems, such as Li2+2xZn1-xGeO4 Li3+xV1-xGexO4, have been relatively well studied. However, other systems...
This work evaluates partially amorphous La0.6Sr0.4CoO3-δ (LSC) as a potential oxygen electrode for low-temperature solid oxide cells. LSC was deposited using the spin-coating technique onto Ce0.8Gd0.2O2-δ (CGO) substrates. The optimal thickness determined 500 nm. electrochemical impedance spectroscopy (EIS) study showed significant improvement in reduction/oxidation reaction kinetics when annealing temperatures below 600 °C. lowest value of polarisation resistance observed sample annealed at...
The thermal behavior of the oxide ion-conducting solid electrolyte Bi4YbO7.5 was investigated using a combination variable temperature X-ray and neutron powder diffraction, analysis (DTA TGA), ac impedance spectroscopy. title compound shows fluorite-type structure throughout measured range (20–850 °C), with phase separation at ca. 600 °C into cubic δ-type an orthorhombic assumed stoichiometry Bi17Yb7O36. This type transition is relatively common feature in bismuth oxide-based systems can...
Total neutron and X-ray scattering 51 V solid-state NMR reveal details of the local structure in BIGEVOX oxide ion conductor. A non-random deficiency next-nearest-neighbour vacancy pairs 〈100〉 tetragonal direction is found.
While BIMEVOX systems have attracted attention for their fast oxide-ion conductivity at intermediate temperatures, there are only a limited number of reports concerning local structure. In this work, both long-range and structures in the Bi2V1–xGaxO5.5–x–δ (BIGAVOX, 0.025 ≤ x 0.40) system investigated using X-ray powder diffraction (XRD) combination total scattering, 51V 71Ga solid-state nuclear magnetic resonance (NMR), Raman spectroscopy, supported by electrical measurements a.c. impedance...
