Sumario:[Image: see text] Uniform Fe(x)Ni(y) nanospheres were synthesized via a simple solvothermal method and used as electrocatalysts for Li–O(2) batteries. Fe(7)Ni(3) nanospheres exhibited relatively high catalytic activities in the electrochemical tests. They delivered a reversible capacity of more than 7000 mAh/g(KB) and gave a discharge–charge voltage gap reduction of 250 mV compared with Ketjen Black.
