The improvement of NMP helps the rapid development of lithium batteries.
The Chinese name of NMP is N -Methy-Pyrrolidone, is a key chemical solvent and extractant in electronic chemicals. Since the 1990s, NMP has risen in the domestic petrochemical industry. After more than 20 years of development, it has gradually been completely localized by the initial basic import. The scope of application has been gradually limited to the petrochemical, coating, pesticide and other industries. Expanded to use in insulation materials and blending solvents, especially lithium-ion batteries, chemical solvents for industrial plastics and printed circuit boards, electronic cleaners for liquid crystal displays.

The role of NMP in the production process of lithium batteries
N-methylpyrrolidone (NMP) is a very important auxiliary material in the production of lithium battery cathode materials. It is a commonly used solvent in the formulation stage of lithium battery cathode materials. According to the lithium battery production process, during the coating and baking stage of lithium battery cathode material production, under the action of circulating hot air, the cathode solvent N-methylpyrrolidone will all volatilize at high temperatures. The gas phase containing NMP is collected and treated through condensation, water spraying, wheel adsorption and concentration and other gas phase collection and treatment measures to form organic liquid containing NMP. By discussing the role, production method, consumption point and purification method of N-Methyl-alpha-pyrrolidonein the production process of lithium battery cathode materials, we hope to achieve on-site purification, conversion and reuse of NMP organic liquid, which can reduce the cost of raw materials and achieve the reduction of lithium battery production enterprises. This efficiency increase.

NMP downstream application and competition pattern
NMP products are mainly used in new energy sources such as lithium-ion batteries and power batteries, and new material industries such as aramid, polyphenylene sulfide and polyimide. With the rapid development of China's emerging industries to pillar industries, the consumption of new energy and new materials in the downstream has increased sharply. Coupled with the technology introduction and self-improvement of the downstream industries, the downstream industrial chain has increased rapidly to meet the needs of national economic and social development.
