1. A process for making a prelithiated lithium ion battery, the process comprising:
subjecting the first battery member to a lithium ion beam comprising lithium ions;
implanting ion beam implanted lithium from the lithium ion beam in the first battery member to prelithiated the first battery member;
disposing a second battery member on a first battery member;
disposing a third battery member on the second battery member so that the second battery member is interposed between the first battery member and the third battery member to form a prelithiated battery composite; and
annealing the prelithiated battery composite to form the prelithiated lithium ion battery such that the prelithiated lithium ion battery has an absence of a solid electrolyte interface composition in a portion of the first battery member subjected to implanting the ion beam implanted lithium from the lithium ion beam.
