Applications

NMP plays a pivotal role in the production of batteries. Its high purity, excellent solvent properties, and stability make it indispensable in achieving the desired performance and longevity of batteries. NMP is widely used as a solvent for binders, electrode slurries and electrolyte preparation.

  • Binder solvent. NMP serves as an effective solvent for battery polymer binders such as polyvinylidene fluoride (PVDF). NMP's viscosity and solubility facilitate efficient and uniform coating of electrode materials.
  • Electrode slurry solvent. NMP is widely used as a solvent for the production of electrode slurries in lithium-ion batteries. It helps in the uniform dispersion of active materials like lithium cobalt oxide (LCO) or lithium iron phosphate (LFP).
  • Electrolyte solvent. NMP is commonly used in the synthesis and formulation of electrolytes for batteries due to its ability to dissolve a wide range of electrolyte salts and additives.
