In this work we report hierarchical Co3O4@NiO nanostrip@nanorod arrays (Co3O4@NiO NSRAs) which are directly grown on three-dimensional conductive substrates by a facile three-step hydrothermal reaction and a following annealing treatment. This hierarchical structure provides several advantages including a large contact surface area, a short ion diffusion path and good charge transport, which validate this film as an advanced electrode for nickel-zinc batteries with both high energy density (5.1 mW h cm(-2)) and power density (82.2 mW cm(-2)).
