Electrode softening agents (also known as flexing agents or plasticizers) are additives used to increase the ductility and flexibility of the electrode layer. These agents are critical during the calendaring (rolling) process, where the electrode is compressed to high densities. Without them, thick or high-capacity coatings are prone to cracking, delamination, or "mud-cracking" during drying or handling. The primary functions of the plasticizer in electrodes are: (1) Stress Relief: They lower the glass transition temperature (Tg) of the binder, making it more rubbery and less brittle. (2) Adhesion Enhancement: By making the binder more compliant, they improve the "wetting" and contact between the active material particles and the current collector foil. (3) Cracking Prevention: They allow the electrode to withstand the high pressures of calendaring and the mechanical strain of battery winding without structural failure. (4) Higher Mass Loading: Softening agents enable the production of thicker electrodes, which are essential for high-energy EV batteries.
