  • Publication number: 20240250238
    Abstract: A composite electrode for an electrochemical cell that cycles lithium ions is manufactured by introducing a solvent, a binder, electroactive material particles, and an electrically conductive agent into a screw extruder to form an electrode precursor mixture. The electrode precursor mixture is discharged from the screw extruder and deposited on a metal substrate to form an electrode precursor layer. The electrode precursor layer is calendared by passing the electrode precursor layer between rollers to adhere the electrode precursor layer to and uniformly distribute the electrode precursor layer over the metal substrate. Then, the electrode precursor layer is dried to remove the solvent therefrom and form a solid electrode layer including the electroactive material particles, the electrically conductive agent, and the binder on the surface of the metal substrate.
