Abstract:Hollow NiCo2O4 microspheres with a highly hierarchical porous structure were synthesized and conducted as catalysts for lithium-oxygen batteries. The influence of NiCo2O4 on the discharge products was investigated. The NiCo2O4 showed the capability to promote the formation of lithium deficient Li2  xO2 and exerted a significant influence on the electrochemical performance of lithium-oxygen batteries with a low charge overpotential and extended full cycling over 50 cycles.
