Why is N-methylpyrrolidone so popular?

First of all, the consumption direction of NMP conforms to the development trend of China. N-methylpyrrolidone accounts for more than 80% of the consumption in the lithium battery industry, and it is a product with absolute voice. In addition, it has its presence in the polymer industry, the pharmaceutical industry, and the electronics industry. Although it does not account for a large proportion in the lithium battery industry, it is also a product with weight.

In the lithium battery industry, as the front-end solvent of lithium batteries, the demand for lithium batteries has increased significantly, which has also driven the high consumption of lithium battery industry and the rapid development of China's NMP in the lithium battery industry. NMP is also an essential chemical solvent for chemical reaction and dilution in the manufacturing process of aramid, polyphenylene sulfide, polyimide and other polymer materials.

Secondly, the rise of NMP's attention cannot be separated from the soaring price of PVDF. The auxiliary materials of lithium battery include solvent and binder. The main role of solvent is to dissolve positive and negative active substances, while the main role of binder is to bond the active substances on the collector. When making electrode sheets, NMP, as a solvent, is mutually soluble with water, PVDF, positive and negative electrode materials and other substances, and fuses various substances required for electrodes, such as adhesives, positive active substances, conductive agents, so that the adhesives and other substances can be fully contacted and evenly distributed. Therefore, as a solvent, NMP directly affects the quality of slurry coating of lithium battery, and indirectly affects the quality of lithium battery.
