The invention discloses a method for preparing a 3D needle-shaped nickel-cobalt bimetallic oxide nano-cluster by a one-step electrodeposition method, which takes pretreated foamed nickel as a substrate, and vertically grows needle-shaped Ni-Co bimetallic oxide on the surface of the substrate by a one-step constant-current electrodeposition method. Meanwhile, the pretreated foam nickel surface has a fine pore structure, so that the template has the function of a template, and has certain capacitance contribution when the loading capacity of active substances on a unit area can be improved, secondary removal is not needed, and the preparation method is simple and efficient. Also provides a novel research idea for the preparation of the linear electrode material and has certain universality. |
