Lithium-ion battery electrodes are manufactured in several stages. Materials are mixed into a slurry, which is then coated onto a foil current collector, dried, and calendared (compressed). The final coating is optimized for electronic conductivity through the solid content of the electrode, and for ionic conductivity through the electrolyte
