Claim 6:
7. A process for making a prelithiated lithium ion battery, the process comprising:
disposing electrode particles in a vacuum environment;
subjecting the electrode particles to a lithium ion beam comprising ion beam implanted lithium;
implanting ion beam implanted lithium from the lithium ion beam in the electrode particles to prelithiated the electrode particles with ion beam implanted lithium;
combining, after implanting ion beam implanted lithium in the electrode particles, the electrode particles with a conductive additive and a binder to form an electrode composition;
disposing, as a first electrode, the electrode composition on a first current collector to form a first electrode member such that the first electrode comprises the ion beam implanted lithium that is present in absence of solid electrolyte interface composition in the first electrode;
annealing the first electrode member; and
disposing the first electrode member on a second electrode member to make the prelithiated lithium ion battery.
