NOVELTY - Manufacturing a porous lithium titanium oxide anode material, involves: (A) mixing a lithium salt and an organic acid to form a starting solution; (B) mixing a titanium salt and the starting solution to form a mixed solution; (C) performing a first heat treatment at 300-800 degrees C; and (D) performing a second heat treatment at 600-800 degrees C, to obtain a porous lithium titanium oxide anode material.    USE - For manufacturing a porous lithium titanium oxide anode material for lithium battery (claimed) useful in mobile devices and as power sources for electric vehicles.    ADVANTAGE - The cost of manufacturing the porous lithium titanium oxide anode material can be reduced through the method, and a lithium battery having excellent electrochemical properties and cycling stabilities can be produced. The porous lithium titanium oxide anode material, is formed by using an economic and easy synthesizing method without requiring an expensive machine. The method of manufacturing the porous lithium titanium oxide anode material is for mass production so as to increase the market value of the resultant manufactured lithium batteries. The porous lithium titanium oxide anode material, increases the contact area with the electrolyte, and reduces the diffusion pathway between electrons and ions to increase the charge/discharge rate and electrochemical properties. Therefore, the battery comprising the porous lithium titanium oxide anode material has excellent cycling stabilities and safety. After performing the charge/discharge process over 200 times, the initial capacity of the battery can still be maintained, which shows that the porous lithium titanium oxide anode material presents excellent cycling stabilities and safety. The cost of manufacturing the porous lithium titanium oxide anode material can be reduced, and the material can be mass-produced and be used for commercial applications. The capacity of the battery is very close to the theoretical capacity (98%), and therefore the usability of lithium batteries can be increased.
