Abstract: Described are pre-lithiated anode active materials, lithium-ion electrochemical cells comprising pre-lithiated anode active materials, methods for preparing pre-lithiated anode active materials, and lithium-ion electrochemical cells comprising pre-lithiated anode active materials. The disclosed processes are useful for adapting various methods for manufacturing for lithium-ion electrochemical cells with modifications to achieve pre-lithiation. The pre-lithiation process used by some embodiments described herein include treating an incomplete lithium-ion cell structure with a lithiation redox agent prior to injecting electrolyte into the cell, using techniques similar to the electrolyte injection process.
