System for roll-to-roll electrocoating of battery electrode coatings onto a foil substrate

Patent ·
OSTI ID:1925041
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.
