英文摘要High-performance anode materials are crucial for developing next-generation high-energy-density lithium-ion batteries (LIBs). In previous reports, NiCo2O4 showed great potential as a candidate anode material for the next-generation LIBs. In this article, we fabricated nanofiber clusters of NiCo2O4-decorated 3D graphene@Nickel foam (NCO@3DGNF) via coupled chemical vapor deposition and NH4F-assisted in situ hydrothermal-anneal route. When the NCO@3DGNF nanocomposite was used as the binder-free electrode for LIBs, the discharge capacity of the nanocomposite reached 707.7 mAh g(-1) after 480 cycles at a current density of 0.5 A g(-1), with good reversibility (Coulomb efficiency is 98-99%) and excellent rate performance. The hierarchical porous structure can not only boost the penetration of electrolytes and ensure rapid electron transport but also buffer the strain caused by lithiation. Therefore, these encouraging results suggest that the NCO@3DGNF composite may be an up-and-coming candidate to replace the anode materials of conventional graphite-based LIBs.
