Application

This compound serves as a highly effective stress-relieving agent in copper foil electrolytes, where it significantly improves material flexibility while reducing brittleness. Its application in electrochemical deposition processes enhances the mechanical properties of deposited metal layers, particularly in PCB manufacturing and lithium-ion battery current collectors. The additive works by modifying the crystallization behavior at the electrode-electrolyte interface, resulting in more ductile metal deposits. Even at low concentrations (typically 0.01-0.1% by weight), it demonstrates remarkable performance in preventing crack formation and improving foil handling characteristics.
