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.

Abstract: Rechargeable battery cells and methods for extreme fast charging are disclosed. For example, such a rechargeable battery cell might be chargeable to at least 70% of usable capacity within 15 minutes. Such a rechargeable battery cell may include an anode containing a Si—C composite within a porous structure, a metal oxide-based cathode configured as a source of Li ions, an electrolyte capable of carrying Li-ions between the anode and the cathode, and a separator between the anode and the cathode. The rechargeable battery may have an interface between the anode and the cathode that is pressurized in an amount sufficient to manage volumetric changes during charging and discharging processes.
