Tokyo Team Discovers Ultrafast Oxide-Ion Conductor
4 min read
A team led by Professor Masatomo Yashima at Science Tokyo discovered a novel Sillén oxybromide, Bi₁.₉Te₀.₁LaO₄.₀₅Br, exhibiting high bulk oxide-ion conductivity of 0.01 S cm⁻¹ at 233 °C. Published in Nature Communications in 2026, the study bridges the Norby gap for solid-oxide fuel cells, offering a route to low-temperature operation by utilizing vacancy-mediated transport mechanisms despite excess oxygen atoms.
