    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: 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: 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.
