    Abstract: A system and method for fast charging of a lithium-ion battery, including: continuously monitoring a state of charge (SOC) of the lithium-ion battery; during a normal mode of operation and upon detecting that the battery is at the predetermined low charge level, discontinuing the discharge; upon detecting that the battery is connected to a charger, providing charging rate of at least 4C for at least part of charging; and upon detecting that the battery, while connected to the charger is at the predetermined high charge level, discontinue the charging, wherein the predetermined low charge level and the predetermined high charge level define a consumable capacity of the battery, wherein the consumable capacity is below 50% of the full capacity of the battery.

    Abstract: 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.

    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.
