Electrode Coating Machine


PNT’s Electrode Coater is a facility that coats and dries the lithium ion battery active material on aluminum and copper foils.

The recent development of lithium-ion battery production facilities is focused on maximizing productivity by running wide-web at high speed. PNT is applying various technologies to meet these needs.

By constructing dry chambers with a length of 80 meters on each floor, the production speed can be maximized up to 100 m/min, enables sequential double-sided coating.

By applying the dry chamber type that opens up and down, energy efficiency has been increased by more than 30% compared to the existing type, and access for maintenance has been improved.
