POSITIVE ELECTRODE ACTIVE MATERIAL AND METHOD OF MANUFACTURING THE SAME, POSITIVE ELECTRODE AND METHOD OF MANUFACTURING THE SAME, AND ELECTROCHEMICAL DEVICE HAVING THE POSITIVE ELECTRODE

摘要

The present invention relates to a positive electrode which comprises a current collector and a positive electrode active material layer formed on the current collector, wherein the positive electrode active material layer consists of a positive electrode active material; the positive electrode active material includes a material which allows for lithium doping and dedoping and a conductive polymer coating layer formed on a surface of the material which allows for lithium doping and dedoping; and the conductive polymer coating layer includes at least one conductive polymer selected from a polyacetylene-based polymer, a polyaniline-based polymer, a polypyrrole-based polymer, a polythiophen-based polymer, a polyphenylene-based polymer, and derivatives of them. Furthermore, the present invention relates to a manufacturing method of the positive electrode, a positive electrode active material, a manufacturing method of the positive electrode active material, and an electrochemical device including the positive electrode.
