CONTROLLED PRE-LITHIATION OF A NEGATIVE ELECTRODE, PRE-LITHIATED NEGATIVE ELECTRODE, AND ALL-SOLID-STATE BATTERY

Disclosed is a method for pre-lithiating a negative electrode for an all-solid-state battery and a negative electrode precursor. The method includes contacting a surface of the negative electrode with a solid electrolyte and applying a first pressure to form a first solid electrolyte layer on the negative electrode, applying additional solid electrolyte on a surface of the first solid electrolyte layer opposite a surface facing the negative electrode and applying a second pressure to form a second solid electrolyte layer on the surface of the first solid electrolyte layer, bringing a lithium metal into contact with a surface of the second solid electrolyte layer opposite a surface facing the first solid electrolyte layer, charging the negative electrode during at least one initial cycle for a duration of time to form a pre-lithiated negative electrode; and removing the lithium metal from the surface of the second solid electrolyte layer.
