  • SYSTEM AND METHOD FOR MULTI-ELECTROLYTE ACTIVATION AND REFURBISHMENT OF ELECTROCHEMICAL CELLS
    Publication number: 20210242550
    Abstract: A method for multi-electrolyte activation or refurbishment of an electrochemical cell uses a first electrolyte to electrochemically decompose electrolyte components onto an electrode surface to create an electrode-electrolyte interphase (EEI). Once the EEI is created, the first electrolyte may be extracted so that a second electrolyte can be introduced into the electrochemical cell. The second electrolyte can interact with the EEI to optimize performance over a broader range of conditions than if the second electrolyte were interacting with the bare electrode. This method also allows for refurbishment of an electrochemical cell. Various structures may be provided on the electrochemical cell itself to facilitate the method.

  • Electrode compositions and processes
    Patent number: 8703333
    Abstract: A composition for use in an electrochemical cell is disclosed wherein the composition includes a clean metal substantially free of impurities and a layer of protective material in contact with the clean metal. Further disclosed is an electrochemical cell including a metal film comprising a clean metal substantially free of impurities. The electrochemical cell may further include an electrolyte and a layer of protective material disposed between the electrolyte and the metal film. A process for manufacturing an electrode is further disclosed including preparing a metal film comprising a clean metal substantially free of impurities and depositing a layer of protective material on to the metal film.
