• NiCo2O4 nanosheets

NiCo2O4 nanosheets supported on Ni foam were synthesized by a solvothermal method. A composite of NiCo2O4 nanosheets/Ni as a carbon-free and binder-free air cathode exhibited an initial discharge capacity of 1762 mAh g(-1) with a low polarization of 0.96 Vat 20 mA g(-1) for sodium-air batteries. Na2O2 nanosheets were firstly observed as the discharged product in sodium-air battery. High electrocatalytic activity of NiCo2O4 nanosheets/Ni made it a promising air electrode for rechargeable sodium-air batteries.
