Abstract

1-methyl-2-pyrrolidone (NMP) is a good solvent with high solubility, high boiling point and high selectivity, which is widely used as a coating solvent in the preparation of cathode materials in the production of lithium-ion batteries. Since NMP is a costly solvent, and the waste gas containing NMP produced in the production process will cause pollution to the environment, it is necessary to recover NMP waste gas. In this paper, we studies the research technologies of NMP in lithium-ion battery production industry and draws some orientation.
