Current collector, electrode, energy storage device, and manufacturing method of energy storage device

Abstract

The object of the present invention is to provide a current collector that can be easily welded even using existing welding methods and whose conductivity can be easily ensured. According to one aspect of the present invention, the current collector is a current collector for an electrode of an energy storage device, characterized in that it comprises a resin layer and a metal layer, the resin layer having a plurality of through holes, the metal layer existing on the surface and back side of the resin layer and on the inner wall of the through holes, and the metal layers on the surface and back side of the resin layer being connected by the metal layer on the inner wall of the through holes. none
