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

Publication number: 20230178755Abstract: A static battery with a non-conductive elastomeric or thermoplastic housing. The, battery housing is adapted to receive at least one anode assembly, at least one cathode assembly, and at least one bipolar electrode assembly. At least the bipolar electrode assembly is formed from a conductive plastic resin that is formed as a CPE sheet. A carbon material is affixed to the CPE sheet to form the bipolar electrode. The at least one cathode assembly, the at least one anode assembly and the at least one bipolar electrode assembly are received into the battery box such that a liquid, and/or gas seal is formed, between electrode assemblies. The battery housing has slots into which the electrode assemblies are received. When the electrode assemblies are received into the housing, cells are formed by the cooperation of the electrode assemblies and the battery housing. The cells are then filled with electrolyte such as zinc bromide and a lid is placed on the battery box.Type: ApplicationFiled: December 5, 2022Publication date: June 8, 2023Applicant: Eos Energy Technology Holdings, LLCInventors: Francis W.
