One-dimensional nanomaterials have been widely studied in energy storage and conversion fields because of their unique structure and physicochemical properties. Sodium-ion batteries are highly promising and attractive for large-scale energy storage due to the truly abundant sodium resources and low cost. With the growing demand of energy and deepening of research, the evolution of structures and properties of one-dimensional nanomaterials are also experiencing from simplicity to complexity and from ordinary to excellence. Therefore, constructing complex superior one-dimensional nanomaterials has become one of the hotspot in energy storage. Based on the new advance in this field and Mai group's work, this review focuses on the construction mechanism and sodium storage performance of complex one-dimensional nanomaterials. These nanomaterials include bundled nanowires, hierarchical zigzag nanowires, mesoporous nanotubes, pea-like nanotubes and ion pre-intercalated nanobelts, which are constructed by organic acid-assisted method, hydrothermal method and electrospinning method, etc. Meanwhile, the relationships between structure and sodium storage performance of complex one-dimensional nanomaterials are also discussed. The above mentioned progresses provide important guidance and assistance for the further development of one-dimensional nanomaterials.
