Unveiling Entropy-Driven Performance Enhancement in Double Perovskite Oxygen Electrodes for Protonic Ceramic Electrochemical Cells (Adv. Energy Mater. 47/2025)
In article number 2503176, Kang Taek Lee and co-workers reveal that entropy-driven lattice disorder in a multicomponent double perovskite optimizes defect chemistry and proton transport. This entropy-engineered oxygen electrode exhibits superior oxygen kinetics and structural stability, achieving record-high reversible performance in protonic ceramic electrochemical cells for efficient power and hydrogen generation..
