The invention relates to a method of recycling an electrode metal material from a waste lithium titanate battery. The method comprises the following steps: step (1) roasting; step (2) acid leaching; step (3) removing Al3<+>; step (4) recovering Li<+>; step (5) recovering and preparing a cathode material; step (6) recovering and preparing an anode material; and step (7) preparing the lithium titanate battery. By taking the waste lithium titanate battery as a raw material to be recycled, environmental pollution is avoided, and meanwhile, the economical benefit is high. The method employing conventional equipment is simple in process flow, easy to control, simple and feasible and green and environmental-friendly, has economical benefits and value, can remove part of impurity elements, and recycles part of metals of a lithium battery.
