Abstract: A linear hierarchical structure lithium titanate material, preparation and application thereof. The crystal phase of the lithium titanate material is a spinel-type crystal phase or a monoclinic crystal phase or a composite crystal phase thereof; the lithium titanate material is mainly composed of a linear hierarchical structure; the linear hierarchical structure has an aspect ratio larger than 10; and the surface components of the linear hierarchical structure are nanosheets. The long-axis of the linear structure facilitates the effective migration of electrons, and the sheet-like hierarchical structure facilitates the rapid intercalation and deintercalation process of lithium ions, sodium ions or potassium ions, and a large specific surface area facilitates the contact area between the electrolyte solution and the electrodes and reduces the current density, thus is excellent in a rapid charge-discharge performance of the battery.
