​Learn about N-methylpyrrolidone
​N-methylpyrrolidone (NMP), as a high-performance green solvent, has shown its unique environmental and performance advantages in many industrial fields.
​Environmental features of NMP
​NMP is a colorless transparent oily liquid with a high boiling point and strong solubility, its chemical formula is C5H9NO, and its molecular weight is 101.13. These characteristics make NMP widely used in industrial production, but they also mean that its disposal and recycling require special attention to environmental issues.
​1. Degradability
​NMP has good biodegradability and can be decomposed by microorganisms in the natural environment, thus reducing environmental pollution. This feature is in line with the concept of green chemistry and sustainable development.
​2 Low volatility
​NMP is less volatile, reducing volatilization losses and air pollution during use. At the same time, this also makes NMP more stable and secure during storage and transportation.
​Performance advantages of NMP in lithium battery production
​Excellent solubility
​NMP is capable of dissolving most organic and inorganic compounds, as well as polar gases and natural and synthetic polymers. This allows NMP to be used as a good solvent for electrode materials in the production of lithium batteries, fusing various substances required for electrodes together to form a uniform electrode structure.
​Improve battery performance
​As a supporting solvent for the positive electrode binder PVDF of lithium battery, NMP can improve the bonding and conductivity of electrode materials, thereby improving the energy density, cycle life and safety of lithium battery.

​​The wide application prospect of NMP
​The concept of green chemistry and sustainable development is deeply rooted in people’s hearts, and NMP as a high-performance green solvent has a broad application prospect in many industrial fields. In addition to lithium battery production, NMP is also widely used in coatings, plastics, chemical production agents, agricultural chemicals, pigments, cleaning agents, insulating materials and other industries. The growing demand for environmentally friendly solvents in these areas provides a broad market space for NMP applications.
