Elmira MEMARZADEH 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).

  • Publication number: 20220407042
    Abstract: An electrochemical cell and a method of preparing the electrochemical cell are provided. The electrochemical cell, such as a lithium battery or a solid-state lithium ion battery, includes a first electrode having a solid polymer electrolyte deposited thereon, wherein the solid polymer electrolyte comprises a microporous polymer swollen with an organic carbonate liquid and a dissociable lithium salt, and a second electrode. The method of preparing an electrochemical cell includes providing the first electrode, immersing the first electrode in an electrolyte solution, depositing the solid polymer electrolyte on the immersed first electrode, and attaching the second electrode to an exposed surface of the solid polymer electrolyte, thereby forming the electrochemical cell. During operation, the solid polymer electrolyte is capable of growing a passivating polymer layer at an interface between the first electrode and the solid polymer electrolyte.

  • Publication number: 20220302438
    Abstract: The present disclosure relates generally to an electrode produced with a non-toxic solvent, resulting in a homogeneous mixture with uniform distributions of a conductive additive and a binder. Electrodes produced according to the present disclosure feature narrow binder particle size distribution, which distinguishes such electrodes from typical electrodes produced via a N-Methyl-Pyrrolidone (NMP) process. The resulting microstructure promotes the flow of current through the electrode and has an improved cycling stability due, in part, to the binder's and the conductive additive's ability to bind with the active material particles used in the fabrication of the electrode.
