A composite of Ni nanoparticles dispersed on N-containing carbon sheets as an electrocatalyst for Li-O2 batteries
Abstract:In this work, we present a facile sol-gel method to prepare a composite of Ni nanoparticles dispersed on N-containing carbon substrates (Ni-C composite). The assembled Li-O2 batteries with Ni-C composite as a cathode catalyst showed lower overpotential and better cyclablity, and the improved performance may be attributed to the superrior electrocatalytic activity of the Ni-C composite.
Keywords: Ni nanoparticles N-containing carbon nanosheets electrochemical activity Li-O2 batteries
