Electrolyte and Separator Plants

electrolyte · separator · support materials

Every cell plant needs three inputs besides cathode and anode powder. The plants that make them are fewer, and more Chinese, than the cell plants they serve.

What the three kinds of plant make. Electrolyte plants blend LiPF6 salt, carbonate solvents and additives such as VC and FEC into electrolyte shipped in drums and ISO tanks. Separator plants extrude polyethylene or polypropylene resin, stretch it by the wet or dry process and apply ceramic coatings to make separator film shipped as slit rolls. Electrode support plants make PVDF, SBR and CMC binders, carbon black and nanotube conductive additives, and aluminum and copper foil for the slurry and coating lines. All three ship to the cell plant.

Finding

Cell plants in North America and Europe still import most of their electrolyte and separator film, so local cell capacity does not mean a local supply chain

Korean and Japanese cell makers brought their suppliers with them: Enchem and Soulbrain built electrolyte plants near LG Energy Solution and SK On sites, and SK IE Technology, Asahi Kasei and W-Scope expanded separator capacity in Poland, Hungary and North America. Chinese suppliers - Tinci, Capchem and SEMCORP - have built plants in Morocco, Hungary and Southeast Asia to serve cell makers outside China.

Entek in Lebanon, Oregon is the main US-owned separator producer; Celgard (Asahi Kasei) makes dry-process film in Charlotte, North Carolina. US-bound Chinese supply faces Section 301 tariffs and foreign-entity-of-concern limits on manufacturing credits.
