The city of Charlotte, North Carolina will play host to President Obama tomorrow as he drops by a fascinating company called Celgard. The high tech company produces a component for lithium-ion batteries—polypropylene (PP), polyethylene (PE), or trilayer PP/PE/PP electrolytic membranes if you really want to know. These batteries can be found in products ranging from cell phones to electric drive vehicles. Celgard recently won $49.2 million in Recovery Act grants to expand its capacity, growth that will create between 200 and 300 new jobs in North Carolina and provide more than 1,000 jobs among Celgard’s contractors and suppliers. These are real jobs held by real people. Learn about the North Carolina company President Obama will on April 4th, 2010. Celgard (a subsidiary of Polypore International, Inc.) in Charlotte produces components for lithium-ion batteries and is a recent Recovery Act grant recipient.
