Publication number: 20240097205Abstract: Provided is a terminal assembly for an electrochemical battery comprising a terminal connector; a conductive flat-plate with an electrically conducting perimeter; an electrically insulating tape member; and a terminal bipolar electrode plate. The electrically insulating tape member is in between the conductive flat-plate and the terminal bipolar electrode plate such that the electrically insulating tape member does not cover the entire surface area of the conductive flat-plate. The electrically conducting perimeter enables bi-directional uniform current flow through the conductive flat-plate between the terminal connector and the terminal bipolar electrode plate. Also provided is a battery frame member for a static rechargeable battery comprising a liquid diversion system; a gutter; a sealing member; a gas channel; and a ventilation hole.Type: ApplicationFiled: November 29, 2023Publication date: March 21, 2024Applicant: Eos Energy Technology Holdings, LLCInventors: George W. Adamson, Sara S. Bowers, Francis W. Richey, Daniel Friberg, Fabian Bruegger, Mateo S. Williams
