NMP Recovery System

Technology for Lithium-Ion Battery Factories

Taikisha's Technology

What is the technology for lithium-ion battery factories?

System capturing NMP from exhaust gas from lithium-ion battery electrodes production.
Reduces refining cost of recovered solvent by minimizing discharge of solvent to the atmosphere and capturing valuable solvents under high concentration.

Can provide solutions to these problems

  • Want to lift productivity
  • Want to reduce CO2 and enhance energy efficiency


Our system, which utilizes proprietary technologies, has one of the best domestic records in the area of small- to large-scale implementation.

This is a revolutionary system which achieves drastic energy savings and a high level of environmental friendliness by recovering NMP used in the manufacturing process of lithium-ion batteries.
This system can recycle exhaust gas as air supply to production equipment at 100%, with NMP recovery efficiency of 99%, and waste heat recovery of 60% or higher.
Since delivering our first system in 1995, we have provided a total of 45 as of 2020.
