Conductive Coating Robotic Spray Process

A robotic spray process has been developed to apply conductive coatings to battery current collectors, fuel cells, and other energy storage devices that require low-resistance coatings. Conductive coatings can improve electrical contact between active materials and the current collector and provide oxidation and corrosion protection. The robotic equipment features an articulated spray head that delivers uniform coatings from all angles. The equipment can spray both epoxy and water-based coatings.
