Abstract: With the emphasis of Chinese government on new energy vehicles,the development trends of power battery mainly includes LFP cell,NMC cell,LTO cell. Owing to its excellent characteristics, long life,high power,high security,etc,LTO battery can be applied to the city bus,storage areas,industrial equipments,etc. In this paper,the development trend,competition pattern,technical field and application market of lithium titanate in China are analyzed and being data mining systematically,which carried out by systematic search for the Chinese patent of lithium titanate. The results of analysis indicate that the preparation technology of lithium titanate is still not mature enough,and the mainstream of lithium titanate preparation technology is still modified. To alleviate or even solve the flatulence problem of lithium titanate battery,the modifications of lithium titanate material and electrolyte, and new formation process are still the main trend. The lithium titanate technology was mainly mastered in China,Japan and the United States,and the main market is in China. The application field of lithium titanate is gradually expanding,but it is mainly concentrated in the field of new energy vehicles and energy storage,and there are very large market potentials in other areas, which will be the future application trends of lithium titanate patents.
