Abstract
The present disclosure relates to a method of synthesis of Lithium Titanate Oxide used for a cathode of Lithium ion battery, the method comprising: (A) diluting TiClwith TiOCl; (B) adding YClor NbClat the rate of 0.1˜2 mol % to Ti(mol); (C) forming a complex salt by dissolving to put at least one selected from a group consisting of Hydroxy propyl cellulose or Polyethylene glycol in a solvent, the Hydroxy propyl cellulose being a complexing agent and being a dispersing agent as well, whereas the Polyethylene glycol being a dispersing agent; (D) synthesizing a titanium precursor by adding an aqueous ammonia solution; (E) preparing Y or Nb doped titanium dioxide(TiO) powder by heat-treating the synthetic product in a temperature of 500˜700° C.; and (F) mixing the Y or Nb doped TiOpowder with LiOH.HO and heat-treating the mixture in a temperature of 800˜900° C.
