Document Type and Number:
WIPO Patent Application WO/2018/105767
Kind Code:
A1
Abstract:
The present invention relates to a paper current collector, a method for manufacturing same, and an electrochemical device comprising a paper current collector. The paper current collector, according to the present invention, is provided with, on top of a fiber layer containing the nanocellulose fiber, conductive layers comprising a conductive material forming a conductive network with the nanocellulose fiber, and thereby provides the advantages of being lightweight, allowing high energy density for an electrode when manufacturing the electrode, having excellent mechanical flexibility, and of securing electrical physical properties and transparency of the material.
