Challenges in Lithium Battery Production
Lithium battery manufacturing involves multiple processes that generate various types of emissions including NMP solvent vapors, electrolyte fumes, and dust from electrode coating and calendering. These emissions require precise temperature control and efficient capture systems to maintain product quality and workplace safety.
Electrode Coating Section
Emission Characteristics
NMP solvent evaporates during coating and drying processes. High-temperature exhaust with consistent concentration levels.
Recommended Treatment
