Interconnected Hollow Nanostructures Containing High Capacity Active Materials For Use In Rechargeable Batteries

View page
US Patent:
8450012, May 28, 2013
Filed:
May 25, 2010
Appl. No.:
12/787138
Inventors:
Yi Cui - Sunnyvale CA, US
Song Han - Foster City CA, US
Ghyrn E. Loveness - Menlo Park CA, US
Assignee:
Amprius, Inc. - Sunnyvale CA
International Classification:
H01M 5/58
H01M 4/90
H01M 4/583
US Classification:
429209, 429220, 4292181, 4292318, 977700, 2521821
Abstract:
Provided are electrode layers for use in rechargeable batteries, such as lithium ion batteries, and related fabrication techniques. These electrode layers have interconnected hollow nanostructures that contain high capacity electrochemically active materials, such as silicon, tin, and germanium. In certain embodiments, a fabrication technique involves forming a nanoscale coating around multiple template structures and at least partially removing and/or shrinking these structures to form hollow cavities. These cavities provide space for the active materials of the nanostructures to swell into during battery cycling. This design helps to reduce the risk of pulverization and to maintain electrical contacts among the nanostructures. It also provides a very high surface area available ionic communication with the electrolyte. The nanostructures have nanoscale shells but may be substantially larger in other dimensions.

Template Electrode Structures For Depositing Active Materials

US Patent:
8556996, Oct 15, 2013
Filed:
Aug 1, 2012
Appl. No.:
13/564324
Inventors:
Ghyrn E. Loveness - Mountain View CA, US
William S. DelHagen - Menlo Park CA, US
Rainer Fasching - Mill Valley CA, US
Song Han - Foster City CA, US
Zuqin Liu - Sunnyvale CA, US
Assignee:
Amprius, Inc. - Sunnyvale CA
International Classification:
H01M 4/13

US Classification:
296231, 429220, 429221, 4292315, 42923195, 429229, 429233, 4292318, 4271261, 977948
Abstract:
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.

Open Structures In Substrates For Electrodes

US Patent:
8637185, Jan 28, 2014
Filed:
Nov 11, 2010
Appl. No.:
12/944596
Inventors:
Eugene M. Berdichevsky - Menlo Park CA, US
Song Han - Foster City CA, US
Yi Cui - Stanford CA, US
Rainer J. Fasching - Mill Valley CA, US
Ghyrn E. Loveness - Menlo Park CA, US
William S. DelHagen - Menlo Park CA, US
Mark C. Platshon - Menlo Park CA, US
Assignee:
Amprius, Inc. - Sunnyvale CA
International Classification:
H01M 4/38
US Classification:
4292181, 429236
Abstract:
Provided are conductive substrates having open structures and fractional void volumes of at least about 25% or, more specifically, or at least about 50% for use in lithium ion batteries. Nanostructured active materials are deposited over such substrates to form battery electrodes. The fractional void volume may help to accommodate swelling of some active materials during cycling. In certain embodiments, overall outer dimensions of the electrode remain substantially the same during cycling, while internal open spaces of the conductive substrate provide space for any volumetric changes in the nanostructured active materials. In specific embodiments, a nanoscale layer of silicon is deposited over a metallic mesh to form a negative electrode. In another embodiment, a conductive substrate is a perforated sheet with multiple openings, such that a nanostructured active material is deposited into the openings but not on the external surfaces of the sheet.

B05D 5/12
H01M 4/82
US Classification:
429209, 427458, 296235, 427 77
Abstract:
Provided are electrode assemblies that contain electrochemically active materials for use in batteries, such as lithium ion batteries. Provided also are methods for fabricating these assemblies. In certain embodiments, fabrication involves one or more electrospinning operations such as, for example, electrospinning to deposit a layer of fibers on a conductive substrate. These fibers may include one or more electrochemically active materials. In the same or other embodiments, these or similar fibers can serve as templates for depositing one or more electrochemically active materials. Some examples of active materials include silicon, tin, and/or germanium. Also provided are electrode fibers that include cores containing a first active material and shells or optionally second shells (surrounding inner shells) containing a second active material. The second active material is electrochemically opposite to the first active material. One or more shells can function as a separator and/or as an electrolyte.

The outer shells may be configured to substantially prevent formation of Solid Electrolyte lnterphase (SEI) layers directly on the inner shells. The conductive cores and/or outer shells may include carbon containing materials. The nanostructures are used to form battery electrodes, in which the nanostructures that are in electronic communication with conductive substrates of the electrodes.

B05D 5/12
US Classification:
429223, 429209, 4292181, 427 77, 427 78, 977700
Abstract:
Provided are novel electrodes for use in lithium ion batteries. 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. An intermediate layer may protect the substrate, help to redistribute catalyst during deposition of the electrochemically active material, improve adhesion between the active material and substrate, and other purposes. 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. Provided also are novel methods of fabricating electrodes containing one or more intermediate layers.
