The key role of N-methylpyrrolidone
In the production process of lithium-ion batteries, N-methylpyrrolidone (NMP) plays a key role as an important solvent. NMP is a nitrogen-containing heterocyclic compound with the following advantages:
Non-toxicity: The use of NMP can reduce potential harm to the environment and human health.
High boiling point: It is stable under high temperature conditions and suitable for the process requirements of battery production.
Strong polarity and high solubility: It can effectively dissolve a variety of materials to ensure the uniformity and stability of electrode coating.
Low viscosity and low corrosiveness: Reduce equipment wear during the production process and extend the service life of the equipment.
Easy to recycle: Helps reduce production costs and environmental impact.
NMP is usually used as a solvent for lithium-ion battery positive electrode coating or a solvent for conductive agent slurry, and is an indispensable auxiliary material in the production of lithium battery electrodes.
Technical value of key material NMP
As the core auxiliary material for lithium battery manufacturing, N-methylpyrrolidone (NMP) is irreplaceable:
Advantages in physical and chemical properties:
Boiling point as high as 202℃, excellent thermal stability
Dielectric constant 32.0, stronger polarity than conventional solvents
Recovery rate can reach more than 95%, meeting green manufacturing requirements
Key points of process application:
Cathode slurry solvent accounts for 80-90%
