Publication number: 20240105914Abstract: Apparatus and techniques described herein can be used to provide a bipolar battery plate with lower resistance as compared to other approaches. In an example, a bipolar plate comprises a conductive current collector substrate with lead-containing surfaces on both sides, onto which active materials are applied. Interfaces with low contact resistance can be created between the active materials and the current collector substrate by a combination of mechanical, thermochemical, and electrochemical techniques. Specifically, the present subject matter can include a bipolar plate fabricated by applying “wet,” (e.g., uncured) active materials to the current collector, and performing a curing procedure such that a corrosion layer with low contact resistance is formed between the active materials and the underlying surfaces of the current collector.Type: ApplicationFiled: January 25, 2022Publication date: March 28, 2024Inventors: Esteban M. Hinojosa, Collin Kwok Leung Mui

Publication number: 20230246164Abstract: A conductive current collector with modified surfaces can be included as a portion of a bipolar battery assembly. The fabrication process can include deposition or formation of a thin film layer such as metal silicide on a surface of the current collector. Metal silicides can be created by co-sputtering or by annealing after deposition of one or more of a silicon or a metal layer. Additional layers can be provided, such as to facilitate adhesion of an active material to a current collector.Type: ApplicationFiled: February 1, 2023Publication date: August 3, 2023Inventors: Collin Kwok-Leung Mui, Esteban M. Hinojosa, Kamran Manteghi

Patent number: 10797276Abstract: Apparatus and techniques such as can include a sealed bipolar battery assembly are described herein. For example, the battery assembly can using two or more sealing techniques, such as to provide a liquid-tight assembly. A sealed current collector assembly can be provided, such as by fitting compressible plastic seals to one or both side of a current collector. An adhesive seal can be applied to an edge or perimeter of the current collector. A plastic seal assembly can be used to anchor the seals or to provide an additional layer of leakage protection should electrolyte seep under hydrophobic plastic seals. Current collector assemblies including stackable casing frames can be assembled to provide a rigid casing. These casing assemblies can be stacked on top of one another to form bipolar cells comprising the battery assembly.Type: GrantFiled: December 30, 2014Date of Patent: October 6, 2020Assignee: Gridtential Energy, Inc.Inventors: Daniel Jason Moomaw, Collin Kwok Leung Mui

Patent number: 10693141Abstract: A current collector assembly, such as for a bipolar lead acid battery, can include an electrically-conductive silicon substrate and a frame bonded to the electrically-conductive silicon substrate. The substrate can be treated or modified, such as to include one or more thin films which render a surface substrate electrically conductive and electrochemically stable in the presence of a lead acid electrolyte chemistry. An interface between the frame and the electrically-conductive silicon substrate can be hermetically sealed. In an example, the frame can provide an edge-seal ring configuration. In an example, a casing assembly can include a spacer bonded to the substrate, along with a casing segment and a thermally-conductive rib, the spacer isolating the thermally-conductive rib from the electrically-conductive silicon substrate electrically.Type: GrantFiled: July 14, 2016Date of Patent: June 23, 2020Assignee: Gridtential Energy, Inc.Inventors: Daniel Jason Moomaw, Collin Kwok Leung Mui, Esteban M.

Publication number: 20180366767Abstract: An end contact, such as for a bipolar battery assembly, can be sized and shaped to provide a low resistance electrical bond between the battery cells and a terminal. In an example, a bipolar battery assembly can include a casing, at least one bipolar current collector housed within the casing, a first monopolar current collector, a first electrolyte region defined between the bipolar current collector and the monopolar current collector, and a first electrically-conductive end contact electrically coupled to the first monopolar current collector. The first electrically-conductive end contact can include a centrally-located hub region, a plurality of planar arms extending radially outward from a centrally-located hub region, and at least one planar brace comprising a first segment extending between two planar arms amongst the plurality of planar arms. A similar end contact can be used for opposite end of the battery assembly.Type: ApplicationFiled: August 24, 2018Publication date: December 20, 2018Inventors: Daniel Jason Moomaw, Collin Kwok Leung Mui, Eduard Schummer
