Description
Summary:•3D porous ZnCo2O4/Co3O4 composite is synthesized on carbon cloth.•High discharge specific capacity of 1350.0 mAh g−1 at 0.1 A g−1 is observed.•The specific capacity retention rate is 64.2% at 0.3 A g−1 after 105 cycles.•The good performance can be ascribed to the synergy effect of ZnCo2O4 and Co3O4. Herein, 3D porous ZnCo2O4/Co3O4 composite grown on carbon cloth is fabricated through in-situ growth of Zn/Co precursor and ZIF-67 following by further annealing to improve the electrochemical performance of single metal oxide. When used as anode material for Li-ion batteries, it exhibits high discharge capacity (1350.0 mAh g−1 at 0.1 A g−1), and long cycling performance (64.2% of the initial capacity is reserved after 105 cycles at 0.3 A g−1). The good performance can be attributed to the porous structure and synergy effect of ZnCo2O4 and Co3O4.
