Calendering of electrodes with enhanced edge quality

A system for manufacturing electrodes with enhanced edge quality, the system comprising:

• an active material supply comprising an electrode material;
• a coating roll coupled to the active material supply, the coating roll positioned to coat a current collector with the electrode material;
• a back roll positioned to transfer the current collector to the coating roll;
• and
• at least one of a bare foil supporting material roll and a coated foil supporting material roll;
• wherein 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;
• wherein 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;
• and
• wherein the support material is applied at a thickness selected to evenly distribute stress across bare portions and coated portions of the current collector during a calendering process, thereby forming a pressed electrode having enhanced edge quality.
