Celgard's History
Celgard® products were initially developed in the mid-1960s at the Celanese Research Labs in Summit, New Jersey, USA. By the mid-1970s, our membranes enjoyed commercial success as a key component in blood oxygenation devices commonly used in open heart surgery. As a subsidiary of Asahi Kasei since 2015, Celgard has been developing and producing separators for primary (single-use) lithium batteries since the early 1980s, and for secondary (rechargeable) lithium batteries since the early 1990s.
Celgard is a wholly-owned subsidiary of Asahi Kasei.
