Title:
COLLECTOR FOR LITHIUM ION BATTERIES AND METHOD FOR PRODUCING SAID COLLECTOR
Document Type and Number:
WIPO Patent Application WO/2021/084900
Kind Code:
A1
Abstract:
A collector for lithium ion batteries according to the present invention is provided with a first conductive resin layer and a second conductive resin layer. The first conductive resin layer contains a first conductive filler. The second conductive resin layer is formed on the first conductive resin layer, and contains a second conductive filler. The first conductive filler is a conductive carbon. The second conductive filler contains at least one metal element that is selected from the group consisting of platinum, gold, silver, copper, nickel and titanium. The volume percentage of the second conductive filler in the second conductive resin layer is larger in a first surface, which is on the first conductive resin layer side, than in a second surface, which is on the reverse side from the first conductive resin layer.
