Abstract: Patches for battery-interfacing devices and associated systems and methods are disclosed. A patch device in accordance with one embodiment includes a storage medium having a patch, the patch including information that is not specific to only the patch device. The patch device can further include a data terminal coupled to the storage medium and coupleable to a corresponding data terminal of a battery port of a host device. The patch is transmissible away from the storage medium via the data terminal. A method in accordance with a particular embodiment includes powering a host device by connecting a battery pack to the host device via a power terminal and a data terminal of the battery pack and corresponding power terminal and data terminal of the host device. Information is conveyed to the host device via the data terminal of the battery pack that is specific to just the battery pack.

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.
