摘要

In this work, nitrogen-doped LaNiO₃ perovskite was prepared and studied, for the first time, as a bifunctional electrocatalyst for oxygen cathode in a rechargeable lithium-oxygen battery. N doping was found to significantly increase the Ni³⁺ contents and oxygen vacancies on the bulk surface of the perovskite, which helped to promote the oxygen reduction reaction and oxygen evolution reaction of the cathode and, therefore, enabled reversible Li₂O₂ formation and decomposition on the cathode surface. As a result, the oxygen cathodes loaded with N-doped LaNiO₃ catalyst showed an improved electrochemical performance in terms of discharge capacity and cycling stability to promise practical Li-O₂ batteries.
