摘要: 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 following annealing treatment. This structure provides several advantages including large contact surface area, short ion diffusion path good charge transport, validate film as an advanced electrode for nickel–zinc batteries with both high energy density (5.1 mW h cm−2) power (82.2 cm−2).
