Summary:A method for regenerating a cathode of a used lithium-ion battery, wherein the cathode of the used lithium-ion battery has a first level of lithium ions, the method comprising providing a pre-lithiation agent to the cathode, assembling a regenerated lithium-ion battery using the cathode with the pre-lithiation agent, and cycling the regenerated lithium-ion battery through at least one full charge event and at least one full discharge event to provide the cathode of the regenerated lithium-ion battery with a second level of lithium ions, wherein the second level of lithium ions is higher than the first level of lithium ions.
