    Abstract: Electrodes, production methods and mono-cell batteries are provided, which comprise active material particles embedded in electrically conductive metallic porous structure, dry-etched anode structures and battery structures with thick anodes and cathodes that have spatially uniform resistance. The metallic porous structure provides electric conductivity, a large volume that supports good ionic conductivity, that in turn reduces directional elongation of the particles during operation, and may enable reduction or removal of binders, conductive additives and/or current collectors to yield electrodes with higher structural stability, lower resistance, possibly higher energy density and longer cycling lifetime. Dry etching treatments may be used to reduce oxidized surfaces of the active material particles, thereby simplifying production methods and enhancing porosity and ionic conductivity of the electrodes. Electrodes may be made thick and used to form mono-cell batteries which are simple to produce and yield high performance.

    Abstract: Single, internally adjustable modular battery systems are provided, for handling power delivery from and to various power systems such as electric vehicles, photovoltaic systems, solar systems, grid-scale battery energy storage systems, home energy storage systems and power walls. Batteries comprise a main fast-charging lithium ion battery (FC), configured to deliver power to the electric vehicle, a supercapacitor-emulating fast-charging lithium ion battery (SCeFC), configured to receive power and deliver power to the FC and/or to the EV and to operate at high rates within a limited operation range of state of charge (SoC), respective module management systems, and a control unit. Both the FC and the SCeFC have anodes based on the same anode active material and the control unit is configured to manage the FC and the SCeFC and manage power delivery to and from the power system(s), to optimize the operation of the FC.

    Abstract: 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.

    Abstract: Lithium ion batteries and electrolytes therefor are provided, which include electrolyte additives having dithioester functional group(s) that stabilize the SEI (solid-electrolyte interface) at the surfaces of the anode material particles, and/or stabilize the CEI (cathode electrolyte interface) at the surfaces of the cathode material particles, and/or act as oxygen scavengers to prevent cell degradation. The electrolyte additives having dithioester functional group(s) may function as polymerization controlling and/or chain transfer agents that regulate the level of polymerization of other electrolyte components, such as VC (vinyl carbonate) and improve the formation and operation of the batteries. The lithium ion batteries may have metalloid-based anodes—including mostly Si, Ge and/or Sn as anode active material particles.

    Abstract: Methods, stacks and electrochemical cells are provided, in which the cell separator is surface-treated prior to attachment to the electrode(s) to form binding sites on the cell separator and enhance binding thereof to the electrode(s), e.g., electrostatically. The cell separator(s) may be attached to the electrode(s) by cold press lamination, wherein the created binding sites are configured to stabilize the cold press lamination electrostatically—forming flexible and durable electrode stacks. Electrode slurry may be deposited on a sacrificial film and then attached to current collector films, avoiding unwanted interactions between materials and in particular solvents involved in the respective slurries. Dried electrode slurry layers may be pressed or calendared against each other to yield thinner, smother and more controllably porous electrodes, as well as higher throughput. The produced stacks may be used in electrochemical cells and in any other type of energy storage device.

    Abstract: 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.

    Abstract: Systems and methods are provided, in which the level of metal ions in cells stacks and lithium ion batteries is regulated in situ, with the electrodes of the cell stack(s) in the respective pouches. Regulation of metal ions may be carried out electrochemically by metal ion sources in the pouches, electrically connected to the electrodes. The position and shape of the metal ion sources may be optimized to create uniform metal ion movements to the electrode surfaces and favorable SEI formation. The metal ion sources may be removable, or comprise a lithium source for lithiating the anodes or cathodes during operation of the battery according to SoH parameters. Regulation of metal ions may be carried out from metal ion sources in separate electrolyte reservoir(s), with circulation of the metal-ion-containing electrolyte through the cell stacks in the pouches prior or during the formation.
