摘要: Abstract NiCo 2 O 4 nanosheets supported on Ni foam were synthesized by a solvothermal method. A composite of nanosheets/Ni as carbon-free and binder-free air cathode exhibited an initial discharge capacity 1762 mAh g − 1 with low polarization 0.96 V at 20 mA g for sodium–air batteries. Na firstly observed the discharged product in battery. High electrocatalytic activity made it promising electrode rechargeable
