摘要

固体氧化物电化学电池在文章编号2503922中，Incheol Jeong, WooChul Jung， Kang Taek Lee及其同事发表了通过F−掺杂稳定δ- bi2o3基氧离子导体的突破性发现。在较低温度下，通过掺入F−调节阴离子亚晶格可以有效抑制δ-Bi2O3的相不稳定性，从而保持其超离子导电性。此外，将掺F−的Bi2O3应用于固体氧化物电化学电池中，使其高效稳定地运行。

Anion Sublattice Engineering via Fluorine Doping to Enhance δ-Bi2O3 Stability for Low-Temperature Solid Oxide Electrochemical Cells (Small 41/2025)

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.
