Uniform Fe x Ni y Nanospheres: Cost-Effective Electrocatalysts for Nonaqueous Rechargeable Li-O2 Batteries.


ABSTRACT: Uniform Fe x Ni y nanospheres were synthesized via a simple solvothermal method and used as electrocatalysts for Li-O2 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.
