Title:

LITHIUM SECONDARY BATTERY POLYMER MATERIAL AND MANUFACTURING METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2019/066219

Kind Code:

A1

Abstract:

The present invention relates to a lithium secondary battery polymer material having both ion conductivity and electron conductivity, and a manufacturing method therefor. The polymer material comprises a blended form of a polythiophene-based polymer and a conductive polymer, and the polymer material can be formed by a manufacturing method comprising the steps of: forming a polythiophene-based polymer; forming a conductive polymer; and heat treating the polythiophene-based polymer and the conductive polymer.
