    Abstract: Anodes for lithium-ion batteries and methods for their production are provided. Anodes comprise an initial anode made of consolidated anode material particles, and a coating of the initial anode, that comprises a layer of an ionic-conductive polymer which provides an artificial SEI (solid-electrolyte interphase) to facilitate lithium ion transfer through the coating while preventing direct fluid communication with the anode material particles and electrolyte contact thereto. The coating may be configured to keep the anode resistance low while preventing electrolyte decomposition thereupon, enhancing cell stability and cycling lifetime.

    Abstract: Charging systems and methods are provided, which increase charging currents and reduce charging durations for battery cells with metalloid-based anodes that enable high C-rate (charging rate) charging. Specifically, methods comprise charging battery cells having metalloid-based anodes having Si, Ge and/or Sn-based anode active material, by providing a high-C charging current of at least 4 C (or 5 C, or 10 C or more) over a range of at least 10-70% SoC (state of charge) of the battery cells. Charging systems comprise a booster unit configured to provide a high-C charging current over at least most of the SoC range of battery cells having metalloid-based anodes in the at least one battery unit. Charging systems further comprise a user interface configured to receive user preferences concerning a specified charging duration and/or a specified target SoC—for implementation by the charging system.

    Abstract: Lithium ion batteries and cells, as well as operating and testing methods are provided, which utilize a transparent pouch to monitor the battery in operational condition and/or in operation. Covers may be used to prevent illumination of battery components when testing is not required, and the covers may be removed or have modifiable transparency configured to enable visual monitoring. Indicators in the transparent pouch may be associated with cell components such as electrodes and electrolyte to indicate their condition. For example, the transparent pouch may be used to monitor battery safety, e.g., by enabling to monitor lithium metallization on an anode (directly or via indicators), monitor battery lifetime and other operational parameters, without having to damage the battery.

    Abstract: Chargers and methods are provided which increase the charging efficiency of the chargers by implementing voltage amplitude modulation (VAM) instead of voltage frequency modulation. The charging voltage amplitude is modulated using feedback from at least one energy storage device that is being charged by the charger, while maintaining a charging voltage frequency constant at a LLC resonance frequency of the charger. A buck/boost configuration may be used to reduce maximal voltage levels and further optimize the charger's design.

    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: 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.
