Lithium (Li) metal is usually considered one of the most promising anode candidates for next-generation batteries owing to its extremely high specific capacity and low reduction potential. However, the application of Li metal anode is still hindered by the uncontrolled growth of dendritic Li and extreme volume fluctuation during cycles. Herein, we demonstrate a flexible and self-supporting 3D interlaced carbon nanofibers coated with 2D ultrathin NiCo₂S₄ nanosheets (denoted as CNF@NiCo₂S₄) which are containing high lithiophilicity and porous structure. This unique structure can significantly reduce the exchange current density and improve the performance for plating Li. Moreover, metallic Li can be further confined within the interspace among the CNF and inside the porous carbon nanoboxes significantly avoiding dendritic Li formation. The CNF@NiCo₂S₄ composite anode exhibits a long-running lifespan for 1000h with an exceptionally low voltage hysteresis. Full cells with LiFePO₄ cathode and LiǀCNF@NiCo₂S₄ anode show typical voltage profiles but enhanced cycle performance than that of LiFePO₄ coupling with bare Li anode at low N/P ratio.
