ABSTRACT:
A system for infiltrating, with active materials, a porous substrate to form electrodes, typically used for batteries, is described that features a vacuum device having a dynamic distribution assembly which allows for continuous and controlled deposition of electrochemical active materials onto a substrate, as the substrate moves therethrough, while preventing the active materials from leaving the vacuum chamber before infiltrating the substrate. The vacuum device includes a vacuum chamber, in fluid communication with a supply of active materials, and a vacuum pump, disposed within the vacuum chamber. The vacuum chamber includes an inlet and an outlet, positioned opposite to the inlet. The first and second opposed major surfaces and a plurality of voids extend therebetween. While disposed within the vacuum chamber, the vacuum pump creates a pressure differential between the first and second surfaces. In this fashion, a quantity of the active materials is drawn into the vacuum chamber, defining detached active material.
