Advanced NMP Recovery Systems for Lithium Batteries – Zschemistry
Ensuring Reliable Lithium Battery Production with Chemically And Thermally Stable NMp Raw Materials
N-Methyl-2-pyrrolidone (NMp) is a solvent that is commonly used in the battery industry because of its excellent chemical and thermal stability. NMp is made from reacting monomethylamine (MMA) and gamma-butyraceous (GBL). It is a colorless to slightly yellow liquid that is heavier than water and has a flashpoint of 100 Celsius. NMp has good chemical and thermal stability because of its high velocity, low volatility, and low toxicity.
NMp is used in the manufacture of lithium-ion batteries, primarily to dissolve the binder polyvinylidene fluoride (PVDF). It has a high boiling point, high polarity, low viscosity, and low volatility. NMp is miscible with water at all temperatures and has good solvency for a wide range of organic and inorganic compounds.
NMp is prone to decomposition when it encounters air and water during use. In the presence of oxygen and water at the same time, NMp can undergo hydrolysis and oxidation reactions at a low temperature of about 120-200°C.
N-Methyl-2-Pyrrolidone (NMp) in Lithium Batteries: Stability And Applications
How does good chemical and thermal stability of lithium battery NMp raw materials?
N-Methyl-2-pyrrolidone (NMp) is a petrochemical solvent with good chemical and thermal stability due to its high polarity, low volatility, and low toxicity. NMp is used in the production of lithium-ion batteries to dissolve the anode binder PVDF, active substances, and conductive agent, and make them into suspension. NMp is also used in pharmaceutical production, chemical processing, and electronics.
NMp is a high boiling, polar aprotic, low viscosity liquid with good solvency for a wide range of organic and inorganic compounds. It is miscible with water at all temperatures and has high chemical and thermal stability.
NMp is used during the coating and baking stage of lithium battery cathode material production, where the cathode solvent N-methyl-pyrrolidinone will all volatilize at high temperatures.

Utilized this set while traveling to the North Pole! wore rain pants for treks when I knew I'd be more active, or compression pants for zodiac rides on really chilly days. Love the lining's fluffy texture. Cleans up easily. Very strongly advised.
