Abstract Multicomponent transition metal compounds (TMCs) composed of many cations and anions have aroused widespread concern on account of their excellent electrochemical properties. Herein, the ZnOHF nanorod anchored to honeycomb-like N-doped porous carbon composite was successfully prepared through a hydrothermal method and used as a novel anode material in lithium-ion batteries (LIBs) for the first time. The specific structure can effectively improve the electronic conductivity, promote electrolyte penetration and accelerate lithium-ion diffusion. Therefore, the ZnOHF/N-C composite exhibits excellent initial discharge capacity (946.8 mAh g−1), high initial coulombic efficiency (ICE, 87.3%) and excellent cyclability (1050.2 mAh g−1 after 430 cycles). What's more, due to the high capacitance contribution of ZnOHF/N-C electrode, it has outstanding rate capability. This study provides a novel idea for the design of multi-component transition metal compound anode materials for LIBs.
