Due to its unique structure and physico-chemical properties, one-dimensional nanomaterials are widely used in energy storage and conversion, etc. Sodium ion batteries are expected to be used for large-scale energy storage because of their abundant sodium resources and low cost. With the development of the one-dimensional nanomaterials, the one-dimensional nanomaterials have evolved from simple to complex and the performance has changed from general to excellent. Therefore, building one-dimensional nanomaterials with complex structure and excellent sodium storage performance has become the key issue of energy storage One of the hot spots in the field.Combining with the current research hot spots and the research progress of our group, this paper mainly elaborates the detailed mechanism of organic acid-assisted drying, hydrothermal method and electrospinning to prepare complex one-dimensional nanomaterials, The properties of the nanomaterials include bundles of nanowires, mesoporous nanotubes, pea-like nanotubes, and pre-embedded nanoribbons. The correlation between their structure and sodium storage performance has been analyzed in detail. Research and application provide some guidance and help.
