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 having at least one surface with a reversible areal capacity, after formation, up to 8.0 mAh/cm2, and a cathode having at least one surface with a reversible areal capacity, after formation, up to 6 mAh/cm2, wherein a ratio of areal capacity of the at least one surface of the anode to the at least one surface of the cathode is between 1.15 to 1.45. Methods of charging rechargeable battery cells disclosed herein under conditions sufficient to enable charging of at least 70% of usable capacity to the rechargeable battery cell within 15 minutes, are also disclosed.

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.
