  • Lithium deposition with multilayer nanomebrane
    Patent number: 10763512
    Abstract: An electrode for a lithium battery constructed of a metal foil current collector, a coating of a pH sensitive polyelectrolyte polymer directly on the metal foil current collector; and a polyelectrolyte polymer nanomembrane comprising alternating layers of oppositely charged polyelectrolyte polymer wherein each succeeding polyelectrolyte layer has excess charge over the previous layer is provided. The pH sensitive polymer may be poly(allylamine hydrochloride) (PAH), poly(dimethyldiallyl ammonium chloride) (PDAD), poly(vinyl pyridine) (PPy), polyethyleneimine (PEI), polyacrylic acid (PAA), polymethacrylic acid (PMA) or poly(styrene sulfonic acid-maleic acid, sodium salt) (PSSM3:1).
    Type: Grant

    Date of Patent: September 1, 2020
    Assignee: Toyota Motor Engineering & Manufacturing North America, Inc.
    Inventors: Claudiu B. Bucur, John Muldoon, Adrian Lita
  • Encapsulated sulfur sub-micron particles as electrode active material
    Patent number: 9819015
    Abstract: A core-shell elemental sulfur sub-micron particle having a core of elemental sulfur and a shell of a membrane containing alternating layers of oppositely charged polyelectrolytes is provided. A functionalized conductive carbon material is optionally present in one or more of the core and an outer layer. A cathode containing the core-shell elemental sulfur sub-micron particle and a lithium-sulfur battery constructed with the cathode are also provided.
