Original Abstract Submitted
aspects of the disclosure include an electrode calendering system for manufacturing electrodes with enhanced edge quality. an exemplary system includes an active material supply including an electrode material and a coating roll coupled to the active material supply. the coating roll is positioned to coat a current collector with the electrode material. a back roll is positioned to transfer the current collector to the coating roll. the system includes at least one of a bare foil supporting material roll and a coated foil supporting material roll. the bare foil supporting material roll is positioned to apply a support material onto a first portion of the current collector prior to the current collector being coated with the electrode material. the coated foil supporting material roll is positioned to apply the support material onto the first portion of the current collector after the current collector is coated with the electrode material.
