Patent number: 11695125Abstract: Apparatuses and methods for depositing materials on both sides of a web while it passes a substantially vertical direction are provided. In particular embodiments, a web does not contact any hardware components during the deposition. A web may be supported before and after the deposition chamber but not inside the deposition chamber. At such support points, the web may be exposed to different conditions (e.g., temperature) than during the deposition. Also provided are substrates having materials deposited on both sides that may be fabricated by the methods and apparatuses.Type: GrantFiled: July 17, 2018Date of Patent: July 4, 2023Assignee: AMPRIUS TECHNOLOGIES, INC.Inventors: Ronald J.

Patent number: 11598872Abstract: A system for enhanced object detection and identification is disclosed. The system provides new capabilities in object detection and identification. The system can be used with a variety of vehicles, such as autonomous cars, human-driven motor vehicles, robots, drones, and aircraft and can detect objects in adverse operating conditions such as heavy rain, snow, or sun glare. Enhanced object detection can also be used to detect objects in the environment around a stationary object. Additionally, such systems can rapidly identify and classify objects based on the encoded information in the emitted or reflected signals from the materials.Type: GrantFiled: December 28, 2020Date of Patent: March 7, 2023Inventors: Rainer J.

Publication number: 20220149379Abstract: Provided are battery electrode structures that maintain high mass loadings (i.e., large amounts per unit area) of high capacity active materials in the electrodes without deteriorating their cycling performance. These mass loading levels correspond to capacities per electrode unit area that are suitable for commercial electrodes even though the active materials are kept thin and generally below their fracture limits. A battery electrode structure may include multiple template layers. An initial template layer may include nanostructures attached to a substrate and have a controlled density. This initial layer may be formed using a controlled thickness source material layer provided, for example, on a substantially inert substrate. Additional one or more template layers are then formed over the initial layer resulting in a multilayer template structure with specific characteristics, such as a surface area, thickness, and porosity.Type: ApplicationFiled: October 4, 2021Publication date: May 12, 2022Inventors: Zuqin Liu, Song Han, Ghyrn E.

Publication number: 20220020979Abstract: Provided are examples of electrochemically active electrode materials, electrodes using such materials, and methods of manufacturing such electrodes. Electrochemically active electrode materials may include a high surface area template containing a metal silicide and a layer of high capacity active material deposited over the template. The template may serve as a mechanical support for the active material and/or an electrical conductor between the active material and, for example, a substrate. Due to the high surface area of the template, even a thin layer of the active material can provide sufficient active material loading and corresponding battery capacity. As such, a thickness of the layer may be maintained below the fracture threshold of the active material used and preserve its structural integrity during battery cycling.Type: ApplicationFiled: May 18, 2021Publication date: January 20, 2022Inventors: Ghyrn E. Loveness, William S. Delhagen, Rainer J. Fasching, Song Han, Zuqin Liu

Patent number: 11228074Abstract: Batteries are described that include a cathode material, and anode material, and a polymeric material that separates the cathode material from the anode material. The polymeric material has hydroxide ion conductivity of at least about 50 mS/cm, and a diffusion ration of hydroxide ions to at least one type of metal ion of at least about 10:1. Also described are methods of making a battery that include forming a layer of polymeric material between a first electrode and second electrode of the battery. In additional methods, the polymeric material is coated on at least one of the electrodes of the battery. In further methods, the polymeric material is admixed with at least one of the electrode materials to make a composite electrode material that is incorporated into the electrode.Type: GrantFiled: November 13, 2019Date of Patent: January 18, 2022Assignee: Apple Inc.Inventors: Steven Kaye, William A.

Patent number: 11121396Abstract: An electrode includes one or more intermediate layers positioned between a substrate and an electrochemically active material. Intermediate layers may be made from chromium, titanium, tantalum, tungsten, nickel, molybdenum, lithium, as well as other materials and their combinations. In certain embodiments, an active material includes one or more high capacity active materials, such as silicon, tin, and germanium. These materials tend to swell during cycling and may loose mechanical and/or electrical connection to the substrate. A flexible intermediate layer may compensate for swelling and provide a robust adhesion interface. Methods of fabricating electrodes involve forming metal silicide nanostructures.Type: GrantFiled: November 5, 2018Date of Patent: September 14, 2021Assignee: Amprius, Inc.Inventors: William S. Delhagen, Rainer J. Fasching, Ghyrn E. Loveness, Song Han, Eugene M. Berdichevsky, Constantin Ionel Stefan, Yi Cui, Mark C. Platshon
