  • Stable electrolyte materials for Li-air battery systems
    Patent number: 10116021
    Abstract: An electrochemical cell in one embodiment includes a first electrode, and a second electrode spaced apart from the first electrode, the second electrode including a substrate of active material, a form of lithium, and a solvent or electrolyte having an electrophilicity index value of less than or equal to 1.1 eV.
    Type: Grant
    Filed: September 14, 2012
    Date of Patent: October 30, 2018
    Assignee: Robert Bosch GmbH
    Inventors: Roel S. Sanchez-Carrera, Boris Kozinsky, Timm Lohmann, Paul Albertus, John F. Christensen
  • Metal/air battery with electrochemical oxygen compression
    Patent number: 9478836
    Abstract: A metal/air battery in one embodiment includes a negative electrode, a positive electrode, and a separator positioned between the negative electrode and the positive electrode, wherein the pressure within the positive electrode is maintained at or above 10 bar with compression energy provided by electrons driving electrochemical reaction in the battery during charging of the metal/air battery.
    Type: Grant

  • Lithium-ion battery with life extension additive
    Patent number: 9048505
    Abstract: A system and/or method for replenishing lithium-ion battery capacity that is lost due to side reactions over the lifetime of a battery in one embodiment includes a battery with a first electrode, a second electrode, a separator region configured to electronically isolate the first and second electrodes, a first portion of lithium metal encapsulated within a first ionically insulating barrier configured to prevent transport of lithium ions therethrough, a memory in which command instructions are stored, and a processor configured to execute the command instructions to (i) determine a first lithium content of the first electrode, (ii) compare the first lithium content of the first electrode to a first threshold, and (iii) activate the first portion of lithium metal based on the comparison of the first lithium content to the first threshold.
