通过自组装技术和随后的热解工艺制备了同轴结构的NiFe2O4/CNTs复合材料。以金属-有机骨架为牺牲性模板制备了多孔结构和NiFe2O4纳米颗粒,颗粒尺寸为5 nm的NiFe2O4均匀分布在碳纳米管的内壁,形成同轴结构。作为锂离子电池负极材料,多孔NiFe2O4/碳纳米管电极在100mA/−1电流密度下循环100次后的可逆容量为624.6 mAg/−1,即使增加到2000mA/g−1,100次循环后仍保持250mAhg−1的容量。这种诱人的电化学性能可能归因于其坚固的同轴结构、良好的孔隙率和畅通的锂离子传输,使其成为潜在的LiBS负极材料。
Coaxial-structure NiFe2O4/CNTs composites are fabricated via self-assembly technique and a subsequent pyrolysis process. Porous structure and NiFe2O4nanoparticles are created by using metal-organic framework as sacrificial templates, and NiFe2O4with the particles size of 5 nm are uniformly distributed along the inside wall of CNTs to form coaxial structure. As an anode material for lithium ion batteries (LIBs), the porous NiFe2O4/CNTs electrode demonstrates a high reversible capacity of 624.6 mAh g−1after 100 cycles at the current density of 100 mA g−1. Even increased to 2000 mA g−1, it still remains the capacity of 250 mAh g−1after 100 cycles. This attractive electrochemical performance may be attributed to its robust coaxial structure, well-marked porosity and unhindered Li-ion transportation, rendering it a potential anode material for LIBs.
