Electrospun NiFe2O4 nanofibers as high capacity anode materials for Li-ion batteries.
Ultra-long NiFe2O4 nanofibers were synthesized by a simple electrospinning process followed by thermal treatment. The NiFe2O4 nanofibers are polycrystalline with average diameter of 218 nm and lengths up to several millimeters. When evaluated for their lithium-storage properties, the electrospun NiFe2O4 nanofibers exhibit a high specific capacity that can exceed 660 mA h g(-1) after 100 cycles, along with enhanced cycling stability.
