Structural regulation, electrocatalytic performance and stability of temperature-modulated high-entropy perovskite cathodes for reversible solid oxide cells

Caption

The temperature-modulated high-entropy perovskite cathodes exhibit increasing lattice distortion (ε= 0.4718－0.5110), abundant oxygen vacancies, and optimized electronic structures, leading to their superior electrocatalytic activity and bifunctional stability. Compared to conventional LSCF-Pm3m cathodes, the HELSCF-Pbnm cathode delivers a higher peak power density, lower polarization resistance, and significantly improved CO2 resistance and long-term cycling performance.
