Summary:The invention discloses a preparation method of chromium lithium titanate, which comprises the following steps of: grinding and uniformly mixing a high-oxidation-state chromium compound, a titanium compound and a lithium compound, adding a small amount of water, continuously grinding into paste, and finally adding an organic reducing agent, grinding and uniformly mixing into non-flowability paste. Transferring the paste into a ceramic crucible, placing the ceramic crucible in a muffle furnace, and initiating a combustion reaction at a certain temperature; after keeping the temperature for a period of time, taking out and cooling to obtain the loose porous green spinel type chromium lithium titanate material. Slightly grinding the material to obtain relatively fine powder; and after carbon coating treatment, the product can be used as a lithium ion battery negative electrode material. The chromium lithium titanate material prepared by the invention has relatively high electrochemical capacity, good stability a
