Abstract

Solid Oxide Electrochemical Cells

In article number 2503922, Incheol Jeong, WooChul Jung, Kang Taek Lee, and co-workers present the groundbreaking discovery to stabilize δ-Bi₂O₃-based oxygen ionic conductors via F⁻ doping. The phase instability of δ-Bi₂O₃ was effectively suppressed at lower temperatures by modulating the anion sublattice through F⁻ incorporation, thereby retaining its superionic conductivity. Furthermore, F⁻-doped Bi₂O₃ was applied to solid oxide electrochemical cells, enabling highly efficient and stable operation.
