Claim 10:
11. A process for making a prelithiated lithium ion battery, the process comprising:
forming a first current collector;
forming a cathode on the first current collector;
forming an electrolyte on the cathode;
forming an anode on the cathode;
subjecting the anode to a lithium ion beam comprising ion beam implanted lithium;
implanting ion beam implanted lithium from the lithium ion beam in the anode to prelithiated the anode with ion beam implanted lithium such that the anode comprises the ion beam implanted lithium that is present in absence of solid electrolyte interface composition in the anode;
annealing the anode after implanting ion beam implanted lithium in the anode;
forming a second current collector on the anode; and
annealing the second current collector to form the prelithiated lithium ion battery.
