  • Separation of electrolytes
    Patent number: 11316204
    Abstract: Methods and articles relating to separation of electrolyte compositions within lithium batteries are provided. The lithium batteries described herein may include an anode having lithium as the active anode species and a cathode having sulfur as the active cathode species. 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 (referred to herein 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 (and referred to herein as an “cathode-side electrolyte solvent”).
    Type: Grant
    Filed: April 17, 2020
    Date of Patent: April 26, 2022
    Assignee: Sion Power Corporation
    Inventors: Yuriy V. Mikhaylik, Chariclea Scordilis-Kelley, Igor P. Kovalev, Cathie Burgess

  • Separation of electrolytes
    Patent number: 10629954
    Abstract: 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.
