DETAILED DESCRIPTION - A molybdenum-doped lithium titanate cathode material comprises 400 pts. wt. lithium titanate, 3-4 pts. wt. molybdenum powder, 2-3 pts. wt. melamine, 3-4 pts. wt. monazite powder, 1-2 pts. wt. sodium metasilicate, 4-5 pts. wt. modified silver powder and proper amount of water, where the modified silver powder is prepared by mixing 100 pts. wt. silver powder, 1-2 pts. wt. nano-carbon, 1-2 pts. wt. kaolin powder, 2-3 pts. wt. TK phosphonium acid ester, 1-2 pts. wt. silicon powder, 1-2 pts. wt. propyldiethoxysilane, 2-3 pts. wt. iron oxide (Fe3O4), 1-2 pts. wt. tin oxide and 1-2 pts. wt. vanadium pentoxide, heating the mixture to 50-55 degrees C, grinding the heated mixture for 1-2 hours, uniformly dispersing the ground mixture to obtain powder, and calcining the powder in furnace at 550-580 degrees C for 2-3 hours to obtain the product. An INDEPENDENT CLAIM is also included for a method for preparing a molybdenum-doped lithium titanate cathode material, which involves mixing the raw materials of the cathode material, grinding the mixture for 2-3 hours to obtain 200-400 meshes slurry, spraying and drying, adding 2-3 wt.% polyethylene wax powder, stirring uniformly and pressing into blank under the pressure of 12-15 Mpa, putting the pressed mixture into a calcining furnace at 620-650 degrees C for 4-5 hours, cooling and crushing the calcined mixture into fine powder of 300-400 meshes to obtain the finished product.
