▎ 摘  要

NOVELTY - Coating electrical current collector involves treating portion of surface of the electrical current collector with adhesion promoting composition to deposit treatment layer over the portion of the surface of the electrical current collector. The resulting surface of the electrical current collector comprises treated portion comprises treatment layer and non-treated portion that lacks the treatment layer. The electrodeposited coating layer is electrodeposited from electrodepositable coating composition onto the surface of the electrical current collector to form coated electrical current collector and rinsed the coated electrical current collector. 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. USE - Method for coating electrical current collector. ADVANTAGE - The method enables to coat electrical current collector that improves wet adhesion. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: a electrode, which comprises electrical current collector having surface, treatment layer on portion of the surface of electrical current collector, portion of the surface of the electrical current collector comprises treatment layer and portion of the surface of electrical current collector lacking the treatment layer and electrodeposited coating layer that is present over the treatment layer; and#a electrical storage device, which comprises electrode, counter-electrode and electrolyte.
