Abstract
Among other things, the present disclosure relates to re-purposing used lithium-ion batteries. The present disclosure includes treating an electrode using a solvent prior to electrochemically relithiating the electrode. In some embodiments, the relithiation may be done using a roll-to-roll device, wherein the electrode may be secured on a first pin and a second pin, then it may be unwound and submerged in an electrolyte solution. Lithium ions may be inserted into the electrode using a voltage. The layer of lithium may provide lithium ions to the electrode.
