Celgard’s Concord, N.C. Facility Achieves ISO/TS 16949 Certification


Charlotte, N.C. – February 25, 2014 – Celgard, LLC, a leading global supplier of microporous separators used in lithium batteries, announces that its Concord, North Carolina, USA, manufacturing facility has achieved certification to the ISO/TS 16949 Quality Management System, enhancing the company’s ability to support the Electric Drive Vehicle (EDV) market.

ISO/TS 16949 is an international quality standard with a set of strict automotive industry-specific requirements. Facility certification is an extensive process, requiring employee training in addition to audits of the procedures a company uses to develop, manufacture and deliver its products. All major vehicle manufacturers are subscribers to the standard, which was created to ensure the integrity of automotive suppliers.

Celgard’s Concord, North Carolina facility is the company’s second location to achieve ISO/TS 16949 certification. Its Charlotte, North Carolina facility received the same accolade in February 2013. Together, the two North Carolina facilities produce the majority of the Celgard lithium battery separator materials used in EDV programs.

“Celgard is widely recognized as a leading industry supplier,” stated Chris Cowger, President of Celgard. “Ensuring that both of our EDV-targeted facilities meet the stringent requirements of ISO/TS 16949 further illustrates our commitment to making the investments needed to support our customers.”

Celgard® separators play a critical role in the performance, life and safety of lithium battery cells by providing a barrier between the positive and negative electrodes – preventing short circuits –while controlling the exchange of lithium ions from one side of the battery to the other. In addition to their function in EDVs, Celgard® separators are widely used in rechargeable lithium-ion batteries for personal electronic devices such as notebook computers, mobile telephones, power tools, reserve power and electricity grid storage systems.
