摘要：

Uniform FexNiy nanospheres were synthesized via a simple solvothermal method and used as electrocatalysts for Li-O-2 batteries. Fe7Ni3 nanospheres exhibited relatively high catalytic activities in the electrochemical tests. They delivered a reversible capacity of more than 7000 mAh/gKB and gave a discharge-charge voltage gap reduction of 250 mV compared with Ketjen Black.
