Abstract
•Hierarchical NiCo2O4 nanorods were synthesized by a hydrothermal method.•NiCo2O4 nanorods as cathode catalysts delivered a high specific capacity of 12,900 mAh g− 1.•NiCo2O4 nanorods exhibited a low charge over-potential and a high rate capability.
NiCo2O4 nanorods were synthesized by a hydrothermal method followed by low temperature calcination. FESEM and TEM analyses confirmed that the as-prepared materials consist of a hierarchical nanorod structure. When applied as cathode catalysts in rechargeable Li–O2 batteries, NiCo2O4 nanorods exhibited a superior catalytic activity, including low charge over-potential, high discharge capacity and high-rate capability.
