摘要：

Rose-like ZnCo2O4 was directly grown on nickel foam via a facile hydrothermal method combined with a subsequent annealing treatment. Self-assembly ZnCo2O4 manifests three dimensional hierarchical architecture and mitigates the volume expansion. The obtained ZnCo2O4 has a large specific surface area of 37.84 m(2) g(-1) and a sufficient pore volume of 0.23 cm(3) g(-1). Porous ZnCo2O4 as a binder-free anode for sodium ion batteries exhibits improved sodium storage capability, ameliorative cycling performance and good structure stability. It remains discharge capacities of 444 and 250 mAh g(-1) after 70 cycles at the current densities of 100 and 500 mA g(-1), respectively.
