The concept of nanostructuring of battery electrodes is not new; it has been frequently employed to improve the charging speed and, in some cases, stability of Li-ion electrodes. Researchers now demonstrated 3D-interconnected Ni nanowire meshes as current collectors and structural scaffolds for building nanostructured Li-ion electrodes. This material exhibits a semi-ordered structure and is characterized by some of the highest combined porosity and surface-to-volume ratio among macroporous metals.
