▎ 摘　　要

A composite cathode including N-rGO with homogeneously dispersed perovskite La0.8Sr0.2Co0.8Fe0.2O3 on the surface is studied. Li-O-2 batteries with LSCF@N-rGO cathode show better performance than those with LSCF-SP or N-rGO cathode. EIS and morphology analysis indicate that LSCF is beneficial to remold the shape of Li2O2 and catalyze the decomposition of Li2O2.
