Ziying Wang has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11949089
    Abstract: An energy storage device can include a cathode, an anode, and a separator between the cathode and the anode. At least one of the electrodes can include an electrode film prepared by a dry process. The electrode film and/or the electrode can comprise a prelithiating material. Processes and apparatuses used for fabricating the electrode and/or electrode film are also described.

  • Publication number: 20230420643
    Abstract: Proposed are methods for manufacturing intermittently coated dry electrodes for energy storage devices and energy storage devices including the intermittently coated dry electrodes. In one embodiment, the method includes providing a metal layer and providing an electrochemically active free-standing film formed of a dry active material. The method also includes combining the electrochemically active free-standing film and the metal layer to form a combined layer. The method further includes removing a portion of the electrochemically active free-standing film from the combined layer so that the electrochemically active free-standing film is intermittently formed on the metal layer in a longitudinal direction of the metal layer.
