Patent number: 11936035Abstract: Core-shell particles, composite anode material, anodes made therefrom, lithium ion cells and methods are provided, which enable production of fast charging lithium ion batteries. The composite anode material has core-shell particles which are configured to receive and release lithium ions at their cores and to have shells that are configured to allow for core expansion upon lithiation. The cores of the core-shell particles are connected to the respective shells by conductive material such as carbon fibers, which may form a network throughout the anode material and possibly interconnect cores of many core-shell particles to enhance the electrical conductivity of the anode. Ionic conductive material and possibly mechanical elements may be incorporated in the core-shell particles to enhance ionic conductivity and mechanical robustness toward expansion and contraction of the cores during lithiation and de-lithiation.Type: GrantFiled: December 25, 2017Date of Patent: March 19, 2024Assignee: STOREDOT LTD.Inventors: David Jacob, Sergey Remizov, Nitzan Shadmi, Hani Farran, Daniel Aronov

Patent number: 10903530Abstract: Improved anodes and cells are provided, which enable fast charging rates with enhanced safety due to much reduced probability of metallization of lithium on the anode, preventing dendrite growth and related risks of fire or explosion. Anodes and/or electrolytes have buffering zones for partly reducing and gradually introducing lithium ions into the anode for lithiation, to prevent lithium ion accumulation at the anode electrolyte interface and consequent metallization and dendrite growth. Various anode active materials and combinations, modifications through nanoparticles and a range of coatings which implement the improved anodes are provided.Type: GrantFiled: April 22, 2019Date of Patent: January 26, 2021Assignee: STOREDOT LTD.Inventors: David Jacob, Sergey Remizov, Nitzan Shadmi, Hani Farran, Daniel Aronov, Boris Brudnik

Patent number: 10637039Abstract: Methods, stacks and electrochemical cells are provided, which improve production processes and yield flexible and durable electrode stacks. Methods comprise depositing an electrode slurry on a sacrificial film to form an electrode thereupon, wherein the electrode slurry comprises a first solvent, attaching (e.g., laminating) a current collector film, which is produced at least partly using a second solvent, onto the formed electrode, to yield a stack, wherein a binding strength of the electrode to the current collector film is higher than a binding strength of the electrode to the sacrificial film, and delaminating the sacrificial film from the electrode while maintaining the attachment of the electrode to the current collector film. Additional layers such as a cell separator and an additional electrode may be further attached using similar steps.Type: GrantFiled: May 7, 2018Date of Patent: April 28, 2020Assignee: Storedot Ltd.Inventors: Sergey Remizov, Boris Brudnik, David Jacob, Daniel Aronov

Publication number: 20130062571Abstract: A method for preparing electrode active material slurry including: mixing a conductive agent and a first thickener with a low molecular weight to primarily disperse the mixture; and mixing an active material and a second thickener with a higher molecular weight than the first thickener in the primary dispersion to secondarily disperse the mixture, and an electrochemical capacitor comprising an electrode using electrode active material slurry prepared by the method. It is possible to prepare a low resistance and high capacity electrochemical capacitor by selectively using at least two thickeners with different degrees of polymerization and molecular weights to remarkably improve dispersibility of an active material and a conductive agent. Particularly, it is possible to reduce resistance based on an electrochemical capacitor with the same capacity.Type: ApplicationFiled: August 9, 2012Publication date: March 14, 2013Applicant: Samsung Electro-MechanicsInventors: Sang Kyun LEE, Seung Min KIM, Ji Sung CHO, Bae Kyun KIM, Sergey Remizov
