[Display omitted] •Synthesis of high-density CuCo2O4 nanosheets via electrodeposition method.•CuCo2O4 nanosheet electrode exhibits a high discharge capacity of 1244mAh/g at 0.1A/g.•Excellent rate capability and stability with 95% capacity retention after 200 cycles. High-density CuCo2O4 nanosheets are grown on Ni foam using electrodeposition followed by air annealing for a Li-ion battery anode. The anode exhibits a high discharge capacity of 1244mAh/g at 0.1A/g (82% coulombic efficiency) and excellent high-rate performance with 95% capacity retention (1100mAh/g after 200 cycles at 1A/g). The outstanding battery performance of the CuCo2O4 anode is attributed to its binder-free direct contact to the current collector and high-density nanosheet morphology. The present experimental findings demonstrate that the electrodeposited binder-free CuCo2O4 material may serve as a safe, low-cost, long-cycle life anode for Li-ion batteries.
