Hierarchical mesoporous CuxCo3-xO4 nanosheets have been directly grown on Ti foil by a facile hydrothermal method and a subsequent annealing treatment. The rich porosity of the sample heated at 600°C (CCO-600) shows excellent electrochemical performance when as anode for Li-ion batteries. It exhibits very high initial discharge capacity of 1300mAhg−1 at 300mAg−1 (1C=1100mAg−1) and achieves reversible charge capacity as high as 335mAhg−1 at the current density of 50C. More importantly, when altering the current density back to 0.1C, the charge capacity could be recovered to 1045mAhg−1.Such high rate capability indicates that this hierarchical mesoporous CuxCo3-xO4 nanosheets material has great potential in lithium ion batteries.
