Slurry dispersion agents (dispersants) are specialized additives that prevent the agglomeration of active materials and conductive carbons. A well-dispersed slurry ensures uniform electrode thickness, lower internal resistance, and improved cycle life. The key benefits of dispersant are: (1) Dispersants break down particle networks, significantly lowering the viscosity of high-solid-content slurries, making them easier to pump and coat. (2) By ensuring conductive additives (like carbon black) are evenly distributed, they create a more efficient electron-transport network throughout the electrode. (3) Better dispersion reduces the occurrence of "pinholes," "fish-eyes," and "mud-cracking" during the drying process. (4) Dispersants prevent sedimentation (settling) of heavy active materials, ensuring the slurry remains consistent from the beginning to the end of a production batch.
