Abstract
A solid lithium cell is formed by stacking an etched copper substrate, a layer of graphite, an electrolyte, and a layer of nickel, manganese, and cobalt oxides. The electrolyte is in contact with the graphite layer and the layer of nickel, manganese, and cobalt oxides. The copper substrate forms the anode of the cell. The layer of nickel, manganese and cobalt oxides forms the cathode of the cell. The electrolyte is a solid lithium-based electrolyte. The graphite layer has a first solid electrolyte interface produced during a pre-lithiation with a liquid lithium-based electrolyte and a second solid electrolyte interface produced during a pre-lithiation with the solid lithium-based electrolyte.
