  • Complex showerhead coating apparatus with electrospray for lithium ion battery
    Patent number: 9685655
    Abstract: A method and apparatus for forming battery active material on a substrate are disclosed. In one embodiment, an apparatus for depositing a battery active material on a surface of a substrate includes a substrate conveyor system for transporting the substrate within the apparatus, a material spray assembly disposed above the substrate conveyor system, and a first heating element disposed adjacent to the material spray assembly above the substrate conveyor system configured to heat the substrate. The material spray assembly has a 2-D array of nozzles configured to electrospray an electrode forming solution on the surface of the substrate.

  • MULTI-LAYER BATTERY ELECTRODE DESIGN FOR ENABLING THICKER ELECTRODE FABRICATION
    Publication number: 20160013480
    Abstract: Implementations of the present invention relate generally to high-capacity energy storage devices and methods and apparatus for fabricating high-capacity energy storage devices. In one implementation, a method for forming a multi-layer cathode structure is provided. The method comprises providing a conductive substrate, depositing a first slurry mixture comprising a cathodically active material to form a first cathode material layer over the conductive substrate, depositing a second slurry mixture comprising a cathodically active material to form a second cathode material layer over the first cathode material layer, and compressing the as-deposited first cathode material layer and the second cathode material layer to achieve a desired porosity.
