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