Publication number: 20200313225Abstract: 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: ApplicationFiled: June 15, 2020Publication date: October 1, 2020Applicant: 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

Patent number: 10629954Abstract: Methods and articles relating to separation of electrolyte compositions within lithium batteries are provided. Suitable electrolytes for the lithium batteries can comprise a heterogeneous electrolyte including a first electrolyte solvent (e.g., dioxolane (DOL)) that partitions towards the anode and is favorable towards the anode (e.g., as an “anode-side electrolyte solvent”) and a second electrolyte solvent (e.g., 1,2-dimethoxyethane (DME)) that partitions towards the cathode and is favorable towards the cathode (e.g., an “cathode-side electrolyte solvent”). By separating the electrolyte solvents during operation of the battery such that the anode-side electrolyte solvent is present disproportionately at the anode and the cathode-side electrolyte solvent is present disproportionately at the cathode, the battery can benefit from desirable characteristics of both electrolyte solvents (e.g.Type: GrantFiled: November 13, 2013Date of Patent: April 21, 2020Assignee: Sion Power CorporationInventors: Yuriy V.
