Patent number: 9048028Abstract: Disclosed herein are systems, devices, and methods for a hybrid electrochemical cell which utilizes two different chemistries in the same cell. According to one aspect, the hybrid cell includes a first pair of electrode units which form a first electrochemical cell and a second pair of electrode units, which form a second electrochemical cell. The second electrochemical cell utilizes a different chemistry than the first electrochemical cells, but both chemistries share a common electrolyte. The hybrid cell further comprises a common electrolyte layer provided between each pair of electrodes. In certain implementations, the common electrolyte layer is a single cavity such that the electrolyte is shared between both the first and the second electrochemical cell.Type: GrantFiled: March 15, 2013Date of Patent: June 2, 2015Assignee: G4 Synergetics, Inc.Inventors: Jon K. West, Julius Regalado, Xin Zhou

Patent number: 8859132Abstract: A stacked energy storage device (ESD) has at least two cell segments arranged in a stack. Each cell segment may have a first electrode unit having a first active material electrode, a second electrode unit having a second active material electrode, and an electrolyte layer between the active material electrodes. Variable volume containment may be used to control the inter-electrode spacing within each cell segment. In some embodiments, one or more dynamic flexible gaskets may be included in each cell segment to seal the electrolyte within the cell segment and to deform in preferred directions. In some embodiments, hard stops may set the inter-electrode spacing of the ESD.Type: GrantFiled: January 27, 2010Date of Patent: October 14, 2014Assignee: G4 Synergetics, Inc.Inventors: Jon Kenneth West, Julius Regalado, Anthony George, Xin Zhou, Nelson Citta, Myles Citta, Allen Michael, Kenneth Cherisol, Daniel J.

Patent number: 8632901Abstract: A stacked battery has at least two cell segments arranged in a stack. Each cell segment may have a first electrode unit having a first active material electrode, a second electrode unit having a second active material electrode, and an electrolyte layer between the active material electrodes. One or more gaskets may be included in each cell segment to seal the electrolyte within the cell segment. The electrode units may be “dish shaped” and may contain a pressure equalization valve to reduce electrode unit deflection and improve pressure equalization between cell segments. The pressure equalization valve may allow a gas to diffuse through adjacent cell segments and may substantially prevent electrolyte from diffusing through.Type: GrantFiled: October 27, 2008Date of Patent: January 21, 2014Assignee: G4 Synergetics, Inc.Inventors: Jon Kenneth West, Martin Patrick Higgins, Julius Regalado, Anthony George

Publication number: 20130011720Abstract: An energy storage device is provided that includes a bipolar conductive substrate having a first side coupled to a first substack and a second side coupled to a second substack. The first and second substacks have a plurality of alternately stacked positive and negative monopolar electrode units. Each respective monopolar electrode unit has a first and second active material electrode layer on opposing sides of a conductive pathway. A separator is provided between adjacent monopolar electrode units. The conductive pathways of the positive monopolar electrode units are electronically coupled to form a positive tabbed current bus, and the conductive pathways of the negative monopolar electrode units are electronically coupled to form a negative tabbed current bus. The negative tabbed current bus of the first substack and the positive tabbed current bus of the second substack are coupled to the first and second side of the bipolar conductive substrate respectively.Type: ApplicationFiled: April 27, 2012Publication date: January 10, 2013Applicant: G4 SYNERGETICS, INC.Inventors: Miles Clark, Kenneth Cherisol, Julius Regalado, Jon K.

Publication number: 20110174084Abstract: Charge information associated with an energy storage device may be determined from one or more kinetic responses of the energy storage device. Kinetic responses may include displacements, forces, pressures, or other kinetic properties, and changes in properties thereof. An indication device, such as a sensor, transducer, or other device, may be used to indicate kinetic responses. Charge information, measurements, or both, may be derived from indications of kinetic responses. Charging or discharging of an energy storage device may be controlled based on charge information.Type: ApplicationFiled: January 14, 2011Publication date: July 21, 2011Applicant: G4 SYNERGETICS, INC.Inventors: Jon K.

Publication number: 20110070488Abstract: Techniques, arrangements and compositions are provided to incorporate nanostructured materials into electrodes for energy storage devices. Materials such as, for example, carbon nanotubes, silicon nanowires, silicon carbide nanowires, zinc nanowires, and other materials may be used to modify electrode properties such as electronic conductivity, thermal conductivity, or durability, for example. In some embodiments, nanostructured materials may be added to electrode formulations such as, for example, slurries or powders. Nanostructured materials may be deposited directly onto active material particles or electrode components. In some embodiments, coatings may be used to assist in deposition.Type: ApplicationFiled: September 21, 2010Publication date: March 24, 2011Applicant: G4 SYNERGETICS, INC.Inventors: Jon K.

Publication number: 20110059362Abstract: Electrode structures may include an electronically conductive foam in contact with an electronically conductive substrate. In some embodiments, the foam may be formed by coating a porous precursor material in contact with a substrate with an electronically conductive material and subsequently removing the precursor material. In some embodiments, the foam may be formed by removing a non-conductive component of a composite material in contact with a substrate, leaving a conductive component in contact with the substrate. Electrode structures may be coated with electronically conductive materials or sintered at elevated temperature to improve durability and conductivity.Type: ApplicationFiled: September 3, 2010Publication date: March 10, 2011Applicant: G4 SYNERGETICS, INC.Inventors: Jon K.
