Abstract:
1. A method for synthesis of high dispersed spherical lithium titanate oxide with yttrium (Y) or niobium (Nb),the method comprising the steps of: (A) diluting titanium tetroxide (TiCl (B) adding yttrium chloride (YCl (C) dissolving in a solvent at least one selected from a group consisting of hydroxypropyl cellulose, which serves as a complexing agent and a dispersing agent, and polyethylene glycol, which serves as a dispersing agent, to form a solution, and adding the solution to the first product of step (B), thereby forming a complex; (D) synthesizing a titanium precursor by adding an aqueous ammonia solution to the complex to form a second product; (E) preparing Y— or Nb—-doped titanium dioxide (TiO (F) mixing said Y— or Nb—-doped TiO
