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: 11831012Abstract: Methods, anode material particles, mixtures, anodes and lithium-ion batteries are provided, having passivated silicon-based particles that enable processing in oxidizing environments such as water-based slurries. Methods comprise forming a mixture of silicon particles with nanoparticles (NPs) and a carbon-based binders and/or surfactants, wherein the NPs comprise at least one of: metalloid oxide NPs, metalloid salt NPs and carbon NPs, reducing the mixture to yield a reduced mixture comprising coated silicon particles with a coating providing a passivation layer (possibly amorphous), and consolidating the reduced mixture to form an anode. It is suggested that the NPs provide nucleation sites for the passivation layer on the surface of the silicon particles—enabling significant anode-formation process simplifications such as using water-based slurries—enabled by disclosed methods and anode active material particles.Type: GrantFiled: April 25, 2019Date of Patent: November 28, 2023Assignee: STOREDOT LTD.Inventors: Ohad Goldbart, 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
