The invention provides a lithium titanate material, a preparation method thereof and a lithium titanate battery containing the lithium titanate material and belongs to the technical field of preparation of a lithium ion battery negative electrode material. The lithium titanate material has a hollow cubic structure. The hollow cubic structure can significantly increase the specific surface area ofthe lithium titanate material, shorten an electron transport path, improve the electronic conductivity of the lithium titanate material and improve the electrochemical kinetic performance. Through thecubic morphology design, the stability of the micron-sized cube morphology is improved and the active crystal face of the nano-sized particles is exposed so that the rate performance and electrochemical activity of the lithium titanate material are improved. Compared with the existing lithium titanate, the lithium titanate material has a better specific surface area, a stable structure and higherreaction activity.
