  • Methods and Devices for Electrochemical Relithiation of Ltihium-Ion Batteries
    Publication number: 20240120568
    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.
    Type: Application

  • LASER ABLATION FOR LITHIUM-ION BATTERIES
    Publication number: 20220263060
    Abstract: The present disclosure relates to utilizing laser ablation to selectively remove regions of active material from lithium-ion battery electrodes during production, forming channels. These channels may improve the radius of curvature of the lithium-ion battery, form patterns on the surface of the electrode to store excess electrolyte, provide improved access to external sources of lithium during pre-lithiation or re-lithiation, and/or lower the tortuosity of electrodes for enhanced ion transfer between electrodes during cycling in prismatic cells and cylindrical cells.
