The Li-Ion Battery industry is a strongly developing field with an interesting prospective for the future. In Li-ion Batteries production, we can highlight three main processes:


  • Electrode production
  • Cells assembly
  • Cells finishing 

Plants designed and produced by airprotech are applied to the electrode production for the treatment of emissions.
A key step in this process is the anode coating and the cathode coating. During these processes the foils, that can be in either copper or aluminium, are covered by a slurry. After the coating, the active material is dried through several dryers by heat. In the anode case, being the active material water-based, gases will be collected in order to recover the heat to be reused in the drying process. In the cathode case, being the active material solvent-based (in particular NMP - Normal Methyl Pyrrolidone), gases will be collected in order to recover the heat and to enable a purification treatment intent to guarantee the compliance with the NMP related emission limits
Being a toxic substance, NMP is regulated by specific guidelines established by the European Union.
Besides being toxic, NMP causes serious irritation to the skin, eyes and respiratory system; furthermore, it is harmful for reproduction as it can damage the foetus.
Airprotech technologies and plants guarantee the highest performances for NMP abatement and recovery, boosting the investment payback, the environmental regulation compliance and the circular economy.



Regenerativ thermische Oxidationsanlagen RTO wurden speziell entwickelt, um die Schadstoffe aus dem Prozessgas durch thermische Oxidation bei hohen Temperaturen zu zerstören.


airprotech liefert VOC Rotor-Konzentratoren auf Zeolithbasis, die typischerweise bei geringer Schadstoffkonzentration und großem Gasdurchsatz installiert werden.


In the Li-Ion Batteries production industry we provide technologies to reduce NMP emissions (N-Methyl-2-Pyrrolidone) through the processes of condensation and adsorption, which enables the recovery and reused of the solvent in the production process.
