Patent number: 11961972Abstract: Provided are flexible multi-battery assemblies and methods of manufacturing these assemblies. In some examples, a flexible multi-battery assembly comprises a first current collector, parsed into a first plurality of current collector portions such that each portion contacts one of a plurality of electrochemically active stacks. The second current collector may be continuous (e.g., to provide support to the electrochemically active stacks) or similarly parsed into a second plurality of current collector portions. Each electrochemically active stack forms one of flexible electrochemical cells in the flexible multi-battery assembly. Furthermore, at least one outer surface of the first current collector or the second outer surface is fully exposed, e.g., to allow forming electrical and mechanical connections directly to one or both current collectors. In some examples, an insulator layer covers a non-exposed surface of the other current collector.Type: GrantFiled: June 25, 2020Date of Patent: April 16, 2024Assignee: CCL LABEL, INC.Inventors: Jesse Smithyman, Konstantin Tikhonov, Christine Ho, Chaojun Shi

Publication number: 20220416306Abstract: Provided are printed electrochemical cells, which utilize zinc salts for ionic transfer, and methods of fabricating such cells. In some examples, a printed electrochemical cell comprises a positive electrode with a positive current collector having a two-dimensional shape and comprising an electrolyte-facing surface formed by the graphite. For example, the positive current collector may be a graphite foil or an aluminum foil with a graphite coating. The cell also comprises electrolyte comprising an electrolyte salt and an electrolyte solvent. For example, the electrolyte salt comprises a zinc salt with a concentration of at least 30% by weight in the electrolyte. The cell is fabricated by printing a positive active material layer over the positive current collector, printing one or more electrolyte layers on various cell components, and laminating a separator layer between the positive and negative electrodes while soaking the separator layer with the electrolyte.Type: ApplicationFiled: June 29, 2022Publication date: December 29, 2022Applicant: Imprint Energy, Inc.Inventors: Konstantin Tikhonov, Chaojun Shi, Christine Ho, Jesse Smithyman, Alex Gurr, Danny Hellebusch, Ehsan Faegh, Albert Aumentado, Pavel Khokhlov

Publication number: 20220384771Abstract: Provided are electronic circuits, comprising electrochemical cells directly integrated with other devices of the circuits, and methods of manufacturing these circuits. The direct integration occurs during cell manufacturing, which allows sharing components, reducing operation steps and failure points, and reducing cost and size of the circuits. For example, a portion of a cell enclosure may be formed by a circuit board, providing direct mechanical integration. More specifically, the cell is fabricated right on the circuit board. In the same or other examples, one or both cell current collectors extend outside of the cell boundary and used by other devices, providing direct electrical integration without a need for intermediate connections and eliminating additional failure points.Type: ApplicationFiled: August 12, 2022Publication date: December 1, 2022Applicant: Imprint Energy, Inc.Inventors: Jesse Smithyman, Konstantin Tikhonov, Christine Ho, Alexander Gurr
