Abstract

In this work, the Co ₃ O ₄ /nitrogen-doped carbon (Co ₃ O ₄ /NDC) composite was prepared by in situ solvothermal method using ionic liquid as carbon and nitrogen sources. The Co ₃ O ₄ /NDC composite was characterized by X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), and electrochemical testing. The HRTEM results show that there is a thin layer of amorphous carbon film on the surface of Co ₃ O ₄ particles, which can improve the conductivity of Co ₃ O ₄ and inhibit the fragmentation of material caused by volume expansion. When the Co ₃ O ₄ /NDC composite is used as the anode material of lithium-ion batteries, the reversible capacity is 1056 mAh g ⁻¹ after 50 cycles at 0.1 C. The superior electrochemical performance can be attributed to the synergistic effect of amorphous carbon film, nitrogen doping, and Co ₃ O ₄ particles.
