Electrode calendering with rollers having controllable sleeves

An electrode calendering system for reducing post-calendering electrode wrinkling, the electrode calendering system comprising:

• at least one roller configured to compress an electrode, the roller defined by an outer surface configured to contact the electrode, the outer surface having a first edge portion at a first side of the roller, a second edge portion at a second side of the roller opposing the first side, and a middle portion disposed between the first edge portion and the second edge portion, the first edge portion and the second edge portion of the roller aligning with first and second outer edges of the electrode when the electrode contacts the roller, the middle portion configured to contact an interior region of the electrode between the first and second outer edges;
• and
• a sleeve disposed about the outer surface of the roller only along the first edge portion, the sleeve having an outer surface configured to contact the first outer edge of the electrode, the sleeve having a controllable thickness extending from the outer surface of the roller to adjust a pressure between the first outer edge of the electrode and the sleeve when the outer surface of the sleeve contacts the first outer edge of the electrode and the middle portion of the outer surface of the roller contacts the interior region of the electrode,
• wherein the sleeve includes a plurality of knitted courses each having loops interlocking with loops of an adjacent knitted course of the plurality of knitted courses, and
• wherein the outer surface of the sleeve has a larger diameter than the middle portion of the outer surface of the roller.
