    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.

    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.

    Abstract: Electrolytes, anode material particles and methods are provided for improving performance and enhancing the safety of lithium ion batteries. Electrolytes may comprise ionic liquid(s) as additives which protect the anode material particles and possibly bind thereto; and/or may comprise a large portion of fluoroethylene carbonate (FEC) and/or vinylene carbonate (VC) as the cyclic carbonate component, and possibly ethyl acetate (EA) and/or ethyl methyl carbonate (EMC) as the linear component; and/or may comprise composite electrolytes having solid electrolyte particles coated by flexible ionic conductive material. Ionic liquid may be used to pre-lithiate in situ the anode material particles. Disclosed electrolytes improve lithium ion conductivity, prevent electrolyte decomposition and/or prevents lithium metallization on the surface of the anode.
