Bismuth Oxides
In article number 2306205, Eric D. Wachsman, Kang Taek Lee, and co‐workers report outstandingly conductive and stable bismuth oxides through a rational triple‐doping strategy. The developed bismuth oxides show ≈140 times higher conductivity than YSZ for 1000 h at 600 °C. Designed low‐temperature solid oxide electrochemical cells, utilizing the bismuth oxides, exhibit exceptional performances...
Despite the great potential of solid oxide electrochemical cells (SOCs) as highly efficient energy conversion devices, the undesirable high operating temperature limits their wider applicability. Herein, a novel approach to developing high‐performance low‐temperature SOCs (LT‐SOCs) is presented through the use of an Er, Y, and Zr triple‐doped bismuth oxide (EYZB). This study demonstrates that EYZB...
