Method for producing lithium-titanium composite oxide doped with different metals, and lithium-titanium composite oxide doped with different metals produced thereby

摘要

The present invention relates to a method for producing a lithium-titanium composite oxide doped with a different metal, and a lithium-titanium composite oxide doped with the different metal produced by the method. Method for producing lithium-titanium composite oxide doped with a dissimilar metal doped by spray-drying method and finely controlled in size of primary particles, and lithium titanium doped with the dissimilar metal produced thereby The present invention relates to a composite oxide. The method for producing a lithium-titanium composite oxide doped with a different metal according to the present invention, and the lithium-titanium composite oxide doped with the different metal produced thereby have a primary particle size larger than that of a conventional lithium-titanium composite oxide. Can be finely adjusted, the production of rutile titanium dioxide can be suppressed, and a battery having high initial charge / discharge efficiency and rate characteristics can be provided.
