NMP production in China reaches international advanced level.
NMP has the advantages of strong solubility, biodegradability and recyclability. It is an indispensable organic solvent in the production of lithium battery."In the process of lithium battery manufacturing, NMP is used as the solution of the polyvinylidene fluoride (PVDF) and the diffusion solution of the lithium battery carbon nanotube conductive paste (CNT)."According to Mr.Liu in EASTCHEM, PVDF is a kind of polymer solid powdery material that can be coated with a liquid solvent of NMP, which can be dissolved and mixed into slurry.The quality of the slurry formed by dissolution has a direct effect on the coating quality and effect of the production section of lithium battery.He also explained that CNT is used to improve the energy density of lithium batteries, and about 95% of CNTS are NMP.
"Our country has a good raw material base for producing NMP."According to Mr.Liu, the main raw materials of NMP are 1, 4-butanediol (BDO). China is the largest BDO producing region in the world and provides a good basis for the development of the NMP industry.
