  • Publication number: 20190267632
    Abstract: Electrochemical cells, and more specifically, release systems for the fabrication of electrochemical cells are described. In particular, release layer arrangements, assemblies, methods and compositions that facilitate the fabrication of electrochemical cell components, such as electrodes, are presented. In some embodiments, methods of fabricating an electrode involve the use of a release layer to separate portions of the electrode from a carrier substrate on which the electrode was fabricated. For example, an intermediate electrode assembly may include, in sequence, an electroactive material layer, a current collector layer, a release layer, and a carrier substrate. The carrier substrate can facilitate handling of the electrode during fabrication and/or assembly, but may be released from the electrode prior to commercial use.

  • Patent number: 10320027
    Abstract: The present invention relates to the application of a force to enhance the performance of an electrochemical cell. The force may comprise, in some instances, an anisotropic force with a component normal to an active surface of the anode of the electrochemical cell. In the embodiments described herein, electrochemical cells (e.g., rechargeable batteries) may undergo a charge/discharge cycle involving deposition of metal (e.g., lithium metal) on a surface of the anode upon charging and reaction of the metal on the anode surface, wherein the metal diffuses from the anode surface, upon discharging. The uniformity with which the metal is deposited on the anode may affect cell performance. For example, when lithium metal is redeposited on an anode, it may, in some cases, deposit unevenly forming a rough surface. The roughened surface may increase the amount of lithium metal available for undesired chemical reactions which may result in decreased cycling lifetime and/or poor cell performance.
