A-site high-entropy perovskite LaFeO3 symmetrical electrode material and preparation method and application thereof
The invention discloses an A-site high-entropy perovskite LaFeO3 symmetrical electrode material and a preparation method and application thereof.The symmetrical electrode material is ABO3 type high-entropy perovskite oxide, the chemical general formula of the high-entropy symmetrical electrode material is La < 0.6 > Ca < 0.1 > Sr < 0.2 > Ba < 0.1 > Fe < 0.8 > Ni < 0.2 > O < 3-delta >, and the high-entropy symmetrical electrode material is prepared through a combustion method. The ABO3 type high-entropy perovskite material can transmit electrons and oxygen ions at the same time, the polarization resistance of the symmetrical oxygen ion conduction type symmetrical solid oxide battery can be effectively reduced, the battery power density and the CO2 electrolysis performance are improved, and the symmetrical electrode material can keep good structural stability in the CO2 atmosphere and can be used for preparing the symmetrical solid oxide battery. And the operation stability of the battery can be effectively enhanced. The symmetrical electrode material is ABO3 type high-entropy perovskite, and the chemical stability of the ABO3 type high-entropy perovskite and electrolyte SSZ is good.
