    Abstract: Methods and supercapacitor-emulating fast-charging batteries are provided. Methods comprise configuring a fast-charging battery to emulate a supercapacitor with given specifications by operating the fast-charging battery only within a partial operation range which is defined according to the given specifications of the supercapacitor and is smaller than 20%, possibly 5% or 1%, of a full operation range of the fast-charging battery. Devices are provided, which comprise control circuitry and a modified fast-charging lithium ion battery having Si, Ge and/or Sn-based anode active material and designed to operate at 5 C at least and within a range of 5% at most around a working point of between 60-80% lithiation of the Si, Ge and/or Sn-based anode active material, wherein the control circuitry is configured to maintain a state of charge (SOC) of the battery within the operation range around the working point.

    Abstract: Systems and methods are provided for balancing battery modules following fast charging, particularly with respect to fast charging lithium ion batteries with metalloid-based anodes. Charge balancing among multiple battery modules connected in series may be carried out by short-circuiting fully charged modules while adjusting the voltage and/or current level supplied by a charger, to fully charge remaining modules. A balancing module comprising a controller and switching circuitry may be configured to implement the charge balancing in association with the charger and its battery management system, and monitoring the battery modules. Advantageously, disclosed switching balancing is more efficient than prior art passive balancing and simpler in implementation than prior art active balancing.

    Abstract: Methods and systems are provided for optimizing usage of a large number of battery cells, some, most or all of which are fast charging cells, and possibly arranged in battery modules—e.g., for operating an electric vehicle power train. Methods comprise deriving an operation profile for the battery cells/modules for a specified operation scenario and specified optimization parameters, operating the battery cells/modules according to the derived operation profile, and monitoring the operation of the battery cells/modules and adjusting the operation profile correspondingly. Systems may be configured to balance cell/module parameters among modules, to have parallel supplemental modules and/or serial supplementary cells in the modules, and/or have supplemental modules and circuits configured to store excessive charging energy for cells groups and/or modules—to increase the cycling lifetime and possibly the efficiency of the systems. Disclosed redundancy management improves battery performance and lifetime.

    Abstract: Electrolytes, anodes, lithium ion cells and methods are provided for preventing lithium metallization in lithium ion batteries to enhance their safety. Electrolytes comprise up to 20% ionic liquid additives which form a mobile solid electrolyte interface during charging of the cell and prevent lithium metallization and electrolyte decomposition on the anode while maintaining the lithium ion mobility at a level which enables fast charging of the batteries. Anodes are typically metalloid-based, for example include silicon, germanium, tin and/or aluminum. A surface layer on the anode bonds, at least some of the ionic liquid additive to form an immobilized layer that provides further protection at the interface between the anode and the electrolyte, prevents metallization of lithium on the former and decomposition of the latter.

    Abstract: The present invention discloses devices and methods for adaptive fast-charging of mobile devices. Methods include the steps of: firstly determining whether a first connected component is charged; upon firstly determining the first connected component isn't charged, secondly determining whether the first connected component is adapted for rapid charging; and upon secondly determining the first connected component is adapted for rapid charging, firstly charging the first connected component at a high charging rate via a charging device. Preferably, the charging device is selected from the group consisting of: a rapid charger and a slave battery. Preferably, the first connected component is selected from the group consisting of: a mobile device and a slave battery. Preferably, the high charging rate is selected from the group consisting of: greater than about 4 C, greater than about 5 C, greater than about 10 C, greater than about 20 C, greater than about 30 C, and greater than about 60 C.

    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.
