Celgard celebrates 15 years at Concord site, expands separator coating capability. 26 May 2026 Celgard has launched new coating capabilities at its Concord, North Carolina manufacturing facility as the lithium-ion battery separator manufacturer marked the site's 15th anniversary. The company said the expansion adds new "state-of-the-art" coating technology capable of producing functional coatings, multilayer coated separators (MCS) and other customised separator products for lithium-ion batteries. According to the company, its new capabilities support a range of coating patterns, thicknesses, coverage levels and multilayer structures, while remaining compatible with multiple base-film technologies. The company said this would enable the development of more tailored separator products for electric vehicles, stationary energy storage systems and next-generation battery applications. Celgard's second US manufacturing site. The Concord plant opened in 2011 as Celgard's second US manufacturing site and forms part of the company's North American manufacturing network. The announcement comes amid the separation of Celgard and lead-acid battery separator specialist Daramic following the sale of Daramic by parent company Asahi Kasei. Celgard describes itself as the original inventor of ceramic-coated separators (CCS), a technology widely used in lithium-ion batteries to improve thermal stability and safety performance. "With our global footprint especially deeply rooted in US, we are excited to drive the LIB industry to a new level with our partners," the company said.
