Abstract: Lithium ion batteries and electrolytes therefor are provided, which include electrolyte additives having dithioester functional group(s) that stabilize the SEI (solid-electrolyte interface) at the surfaces of the anode material particles, and/or stabilize the CEI (cathode electrolyte interface) at the surfaces of the cathode material particles, and/or act as oxygen scavengers to prevent cell degradation. The electrolyte additives having dithioester functional group(s) may function as polymerization controlling and/or chain transfer agents that regulate the level of polymerization of other electrolyte components, such as VC (vinyl carbonate) and improve the formation and operation of the batteries. The lithium ion batteries may have metalloid-based anodes—including mostly Si, Ge and/or Sn as anode active material particles.

Abstract: Prelithiation methods and fast charging lithium ion cell are provided, which combine high energy density and high power density. Several structural and chemical modifications are disclosed to enable combination of features that achieve both goals simultaneously in fast charging cells having long cycling lifetime. The cells have anodes with high content of Si, Ge and/or Sn as principal anode material, and cathodes providing a relatively low C/A ratio, with the anodes being prelithiated to have a high lithium content, provided by a prelithiation algorithm. Disclosed algorithms determine lithium content achieved through prelithiation by optimizing the electrolyte to increase cycling lifetime, adjusting energy density with respect to other cell parameters, and possibly reducing the C/A ratio to maintain the required cycling 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: A charging system that may include a booster unit; a main charging unit that has a charging capability and is configured to use, during a first charging phase, a first part of the charging capacity for charging battery cells by providing a high-C charging current of at least 4 C. The main charging unit is further configured to use a second part of the charging capacity, during the first charging phase, to charge the booster unit. The first part of the charging capacity is limited by a first charging current limitation of the battery cells.
