The role of NMP in the battery
The most commonly used solvent in the pre-treatment of lithium-ion batteries is NMP, commonly known as methyl, known as N-methylpyrrolidone, and the molecular formula is C5H9NO. The role of NMP in the battery: as a PVDF solvent, participate in the dispersion of the slurry, form a uniform medium, and maintain a stable slurry for a long time in a certain viscosity range.

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.
