The present invention is directed toward a coating system for electrodepositing a battery electrode coating onto a foil substrate, the system comprising a tank structured and arranged to hold an electrodepositable coating composition; a feed roller positioned outside of the tank structured and arranged to feed the foil into the tank; at least one counter electrode positioned inside the tank, the counter electrode in electrical communication with the foil during operation of the system to thereby deposit the battery electrode coating onto the foil; and an in-line foil drier positioned outside the tank structured and arranged to receive the coated foil from the tank. Also disclosed are methods for electrocoating battery electrode coatings onto conductive foil substrates, coated foil substrates, and electrical storage devices comprising the coated foil substrates.

Graphene is formed with a practically uniform thickness on an uneven object. The object is immersed in a graphene oxide solution, and then taken out of the solution and dried; alternatively, the object and an electrode are immersed therein and voltage is applied between the electrode and the object used as an anode. Graphene oxide is negatively charged, and thus is drawn to and deposited on a surface of the object, with a practically uniform thickness. After that, the object is heated in vacuum or a reducing atmosphere, so that the graphene oxide is reduced to be graphene. In this manner, a graphene layer with a practically uniform thickness can be formed even on a surface of the uneven object.

An electrodeposition dispersion of the present invention is formed of a dispersion medium and a solid content. The solid content includes polyimide-based resin particles and fluorine resin particles. Also, a content ratio of the fluorine resin particles in the solid content is 20 to 70% by mass. In addition, a median diameter of the polyimide-based resin particles is 50 to 400 nm.
