Determining the average zeta potential and distribution of battery electrode slurry

In this application note from Bettersize Instruments, explore how in recent years, the rapid development of the new energy industry has highlighted the significant role of lithium batteries as reusable and rechargeable batteries in various industrial applications. During the production process of lithium batteries, electrode slurry is formulated using n-methylpyrrolidone (NMP) as a dispersant. NMP serves as a solvent for polyvinylidene fluoride (PVDF) during the slurry batching stage, aiding in the dispersion of the slurry to create a more uniform system. In addition, NMP acts as the primary carrier of the slurry during the coating stage, ensuring even coating on the substrate. Furthermore, during the coating and baking stages, NMP volatilizes and creates pores in the coating, resulting in a uniformly distributed porous microelectrode structure.
