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.
通过简单的静电纺丝工艺并经过热处理合成了超长的NiFe2O4纳米纤维。NiFe2O4纳米纤维为多晶结构，平均直径为218纳米，长度可达几毫米。在对其储锂性能进行评估时，静电纺丝的NiFe2O4纳米纤维表现出高比容量，在100次循环后可超过660 mA h g(-1)，同时循环稳定性增强。
