    Abstract: Particles of active electrode material for a lithium-ion cell are suspended in an atmospheric plasma-activated gas stream and deposited on a surface of a metal current collector foil having a surface film of an oxide of the metal. The metal oxide film-containing surface of the current collector is pre-coated with a thin layer of an electrically conductive organic polymer composition that serves as a bonding surface for the plasma-applied particles of electrode material. For example, a non-conductive polymer (such as polyvinylidene difluoride) may be filled with carbon particles or copper particles. The polymer layer is typically only a few micrometers in thickness and composed to be compatible with the plasma-applied electrode material particles and to conduct electrons between the oxide film-coated, metal current collector and the deposited electrode layer.

  • Publication number: 20170324113
    Abstract: Provided are negative electrode assemblies containing lithium sulfide anolyte layers, electrochemical cells including these assemblies, and methods of forming thereof. An anolyte layer may be disposed over a metal layer of a current collector and may be used to separate the current collector from the rest of the electrolyte. The metal layer may include copper or any other suitable metal that forms in situ a metal sulfide during fabrication of the electrode assembly. Specifically, a sulfur containing layer, such as a solid electrolyte, is formed on the metal layer. Sulfur from this layer reacts with the metal of the current collector and forms a metal sulfide layer. When lithium is later added to the metal sulfide layer, a lithium sulfide anolyte layer is formed while the metal layer is recovered. Most, if not all operations may, be performed in situ during fabrication of electrochemical cells.

    Abstract: Power storage system includes battery containing an electrolytic solution, and ECU that controls permission and prohibition of charge/discharge of battery based on inside temperature of battery. ECU sets determination temperature equal to or higher than freezing point of the electrolytic solution and determination temperature higher than determination temperature. ECU prohibits charge/discharge of battery when inside temperature falls below determination temperature while the electrolytic solution is in a liquid state, and cancels the prohibition of charge/discharge of battery when the electrolytic solution turns into the liquid state from a state in which the electrolytic solution is at least partially solidified, and when the temperature of battery exceeds determination temperature.

    Abstract: Artifacts from the presence of a reference electrode in a thin-film cell configuration can be minimized or eliminated by providing the surface of a reference electrode with a specified surface resistivity. Theoretical considerations are set forth that show that for a given wire size, there is a theoretical surface resistance (or resistivity) that negates all artifacts from the presence of the reference wire. The theory and the experimental results hold for a electrochemical cell in a thin-film configuration.
