Abstract
The disclosure relates to pre-lithiation for batteries having silicon anodes. One example embodiment is a method. The method includes applying a voltage across an anode and a cathode of a battery during a formation charging process. The method also includes transferring lithium ions from the cathode to the anode to perform in situ pre-lithiation. A ratio of a capacity of the anode to a capacity of the cathode is less than 1.0.
