A titanium-containing active material for negative electrodes and its production method, and a titanium-containing power lithium battery. The titanium-containing active material for negative electrodes has a general formula of Li 4 Ti 5 O 12 /M x , wherein Li 4 Ti 5 O 12 is spinel lithium titanate, M is a doping substance selected from a metal element, metal compound, non-metal substance or non-metal compound, and 0<x≤10; an element or ion of said doping substance enters into the lattice matrix of Li 4 Ti 5 O 12 or combines with Li 4 Ti 5 O 12 . The production method for the titanium-containing active material includes the following steps: a mixture of a composite lithium titanate precursor is produced and heat treated after spray drying. The titanium-containing power lithium battery uses Li 4 Ti 5 O 12 /M x as an active material for negative electrodes. |
