Abstract:
The present invention is directed to a method of coating an electrical current collector comprising treating a portion of a surface of the electrical current collector with an adhesion promoting composition to deposit a treatment layer over the portion of the surface of the electrical current collector, wherein the resulting surface of the electrical current collector comprises (a) a treated portion comprising the treatment layer and (b) a non-treated portion that lacks the treatment layer; electrodepositing an electrodeposited coating layer from an electrodepositable coating composition onto the surface of the electrical current collector to form a coated electrical current collector; and rinsing the coated electrical current collector, wherein the electrodeposited coating layer substantially adheres to the treated portion of the surface and does not adhere to the non-treated portion of the surface. Also disclosed are electrodes and electrical storage devices.
