Original Abstract Submitted

system for control and optimization of a coated secondary battery electrode drying process includes a closed-loop process control module that is configured to process manufacturing data derived from a sheet production apparatus for coating a metal sheet with electrode material. the electrode production system includes: a continuous source of a sheet of metal substrate; a coater that is configured to apply electrode material to form a coated moving sheet; an oven that equipped with a heat source to remove solvent from the coat to form a dried coated moving sheet; means for determining the residual solvent content in the dried coated moving sheet and generating representative signals; and controller means for controlling the intensity of the heat source in response to the signals to maintain the residual solvent content at a desired level.
