Claim 13:
14. A process for making a prelithiated lithium ion battery, the process comprising:
forming a first current collector;
forming a second current collector;
forming a cathode on the first current collector, the cathode comprising an interdigitated structure that is in electrical communication with the first current collector;
forming an anode on the second current collector, the anode comprising a second interdigitated structure that is in electrical communication with the second current collector;
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 and the cathode after implanting ion beam implanted lithium in the anode; and
disposing an electrolyte on the on the cathode and the anode so that lithium ions are communicated through the electrolyte from the anode to the cathode or from the cathode to the anode to make the prelithiated lithium ion battery.
