Abstract

Electrochemical Cells

In article number 2304059, Sun-Ju Song, Chan-Woo Lee,WooChul Jung, Kang Taek Lee, and co-workers unveil the role of bimetal-doped BaCoO_3−𝛿 (BCO) for highly active oxygen electrodes of protonic ceramic electrochemical cells. Through bimetal doping, the hexagonal structure of BCO is transformed into a cubic perovskite, leading to improved transport of all charge carriers (H⁺/O²⁻/e⁻).

论掺杂双金属的 BaCoO3-𝛿 Perovskites 作为质子陶瓷电化学电池高活性氧电极的作用（Adv.）

电化学电池在文章编号 2304059 中，Sun-Ju Song、Chan-Woo Lee、WooChul Jung、Kang Taek Lee 及其合作者揭示了双金属掺杂的 BaCoO3-𝛿 (BCO) 在质子陶瓷电化学电池的高活性氧电极中的作用。通过双金属掺杂，BCO 的六方结构转变为立方包晶，从而改善了所有电荷载流子（H+/O2-/e-）的传输。
