Abstract
The present application describes a method of forming an energy storage device that directly adds a lithium layer (such as a lithium foil or otherwise deposited lithium) into the cell stack during cell assembly for prelithiating. The method includes providing a silicon-based anode, providing a cathode, positioning a separator between the anode and the cathode, and disposing a lithium layer between the silicon-based anode and the separator, such that the lithium layer is in contact with the anode.
