Nanomaterials are often categorized based on number of dimensions of a material, which are outside the nanoscale (<100 nm) range. Accordingly, in one-dimensional nanomaterials (1D), one dimension is outside the nanoscale. This class includes nanofibers, nanotubes, nanorods, and nanowires. 1D materials are generally considered to be high‐capacity and stable electrode materials, due to their uniform structure, orientated…
