Abstract
A current collector which uses a conductive primer layer under an electrode layer to improve the contact and adhesion of the electrode layer to a supporting member, wherein the conductive primer layer is composed of a polymeric material having pendant carboxylic acid groups crosslinked with a multifunctional crosslinking agent, and a conductive filler. The current collector may be used inter alia for making batteries.
