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: 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: 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: 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: 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 of managing a lithium ion battery and of recovering branches and/or cells in the battery are provided, as well as battery management systems (BMS) and batteries implementing the methods. Branches and/or cells may be recovered by slow and deep discharging, followed by slow charging—to increase capacity, cycling lifetime and/or enhance safety thereof. BMSs may be configured to diagnose defective branches and/or cells and manage the recovery procedure with respect to changing operational loads the battery and the available internal and external charging sources.
