▎ 摘　　要

NOVELTY - Method for preparing modified lithium titanate composite material, involves calcining titanium source, lithium source, and first aluminum source by wet method for one time to obtain a mixture of titanium titanate and lithium aluminum oxide, mixing at least one of the second aluminum source and conductive agent with the mixture, and then calcining at a time of secondary calcining. USE - The method is useful for preparing modified lithium titanate composite material, which is useful in a cathode ion battery and a lithium-ion battery. ADVANTAGE - The method enables to preparation of modified lithium titanate composite material, which has high multiplying power performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a modified lithium titanate composite material. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram of the method for preparing a modified lithium titanate composite material. (Drawing includes non-English language text).
