Electrode Coating

Yasui Seiki’s cutting edge coating machines are capable of handling and coating on thin metal foils. We can coat both anode (e.g. graphite) and cathode (e.g. LiCoO3) slurries onto, on average 6 to 25 micron thin, current collector materials, such as aluminum, copper, titanium and nickel foils. The coating thickness is purpose dependent and it varies between 10 to 250 micron thick. We use slot die coating methods for the slurry coating at our facility. We also often primer coat the thin foils prior to the slurry coating to improve performance. Both MICROGRAVURE™ and slot die can be arranged to lay down multiple, continuous stripes as necessary.
