CARBON COATING METHOD OF LITHIUM TITANIUM OXIDE NANOPARTICLE AND CARBON-COATED NANOPARTICLE MADE BY USING IT |
摘要 |
PURPOSE: A carbon-coating method of a lithium titanium oxide-based negative electrode active material is provided to provide a negative electrode active material nanoparticle with excellent electric conductivity and ion conductivity, high electrochemical performance, and high discharging rate. CONSTITUTION: A carbon-coating method of a lithium titanium oxide-based negative electrode active material comprises: a step of forming a solution including a negative electrode active material represented by chemical formula: Li4Ti5O12 under the condition; a step of separating a negative electrode active material nanoparticle from the solution; and a step of inserting the negative electrode active material nanoparticle, and coating the surface of the nanoparticle.
