In this work, we present a facile sol–gel method to prepare a composite of Co nanoparticles highly dispersed on N-rich carbon substrates (Co–C composite). The assembled Li–O2 batteries with the composite as a cathode catalyst showed lower overpotential and better cyclability, and the improved performance may be attributed to the superior electrocatalytic activity of the Co–C composite.
