Asahi Kasei has officially opened a wet-process separator coating line at Celgard's manufacturing facility in Charlotte, North Carolina, marking a significant expansion in the U.S. battery supply chain. The new line will produce coated battery separators, a critical component in lithium-ion cells that prevents the positive and negative electrodes from short-circuiting while allowing ions to flow. The move underscores the growing push to localize battery materials production in North America, reducing dependence on Asian suppliers as the EV market accelerates. The partnership between the Japanese chemical giant and the American separator specialist highlights how cross-border collaboration continues to shape the competitive landscape of next-generation battery manufacturing.
