PREPARATION METHOD OF LTO/AC COMPOSITE MATERIAL HAVING LTO FORMED ON AC SURFACE, AND A FABRICATION METHOD OF AN ELECTROCHEMICAL CAPACITOR USING THE PREPARED LTO/AC COMPOSITE MATERIAL

Document Type and Number:

WIPO Patent Application WO/2011/052852

Kind Code:

A1

Abstract:

The present invention relates to a preparation method of an LTO/AC composite material having a lithium titanium oxide (LTO) formed on the surface of activated carbon (AC), and a fabrication method of an electrochemical capacitor using the prepared LTO/AC composite material. In particular, the present invention relates to a hybrid capacitor using AC as an anode material and a composite material having LTO formed on the AC surface as a cathode material, thereby capable of implementing the physical adsorption-desorption reaction principles of ions contained in an electric double layer capacitor as well as the electrochemical reaction of lithium ions contained in the LTO material.
