Patent number: 11121397Abstract: 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.Type: GrantFiled: November 25, 2019Date of Patent: September 14, 2021Assignee: Sion Power CorporationInventors: Chariclea Scordilis-Kelley, John D. Affinito, Lowell D. Jones, Yuriy V. Mikhaylik, Igor P. Kovalev, William F. Wilkening, Christopher T. S. Campbell, John A. Martens
