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 *as found to significantly increase the Ni3+ contents and oxygen vacancies on the bulk-surface of the perovskite, which helped to prom-Ote the oxygen reduction reaction ancLoxygen evolution reaction of the cathode ancloherefore, enabled reversible Li-2-O-2 formation and decomposition on the cathode surface. AS a result, the oxygen cathodes loaded with N-doped LaNiO3 catalyst showed an improved electrO-chemical performance in terms. of discharge capacity and cycling stability to promise practical Li-O-2 batteries.
