Abstract

Chrysanthemum flower-like NiCo₂O₄-nitrogen doped graphene oxide composite material has been explored as a bifunctional cathode electrocatalyst for aqueous zinc-air and non-aqueous lithium-oxygen batteries. This cathode exhibits maximum discharge capacities of 712 and 15 046 mA h g^-1 for zinc-air and lithium-oxygen batteries, respectively, with stable cycling over 50 cycles.
