In lithium battery production, NMP (N-Methyl pyrrolidone), a critical solvent, is widely applied to dissolve binders including PVDF (Polyvinylidene Fluoride) for preparing cathode slurry. However, NMP features corrosive nature, posing risks to production equipment and battery performance, necessitating its removal through baking processes. Additionally, NMP’s flammability and explosivity at concentrations beyond the Lower Explosive Limit (LEL) demand rigorous safety controls. Accurate NMP detection will directly have impacts on battery performance, equipment integrity, and personnel safety. Therefore, it is vital to monitor NMP in manufacturing facilities.
