Abstract:
CoFe2O4 nanoparticles were uniformly anchored on reduced graphene oxide by a facile solvothermal method. The obtained CoFe2O4/reduced graphene oxide (CoFe2O4/rGO) hybrid was employed as catalyst for Li-O2 batteries. It could effectively lower the ORR (oxygen reduction reaction) and OER (oxygen evolution reaction) overpotentials of the batteries and deliver a large capacity of 12 235 mA h grGO(-1) (2116 mA h ghybrid(-1)). It also exhibited high cyclic stability.
