Celgard, a subsidiary of Polypore International (NYSE: PPO) and Panasonic have agreed to work together to develop coated and uncoated Celgard brand separators for Panasonic’s next-generation cylindrical battery cells. Upon completion of the development effort, the two firms expect to form a long term supply agreement.

A battery separator provides a barrier between the anode and the cathode while enabling the exchange of lithium ions. Celgard’s current separators are polypropylene (PP), polyethylene (PE), or trilayer PP/PE/PP electrolytic separator membranes.

“We are pleased to work with an industry leader such as Panasonic on this development initiative and to further solidify our partnership with them. It demonstrates the commitment of both of our companies to improve lithium-ion battery technology and meet ever-increasing demands in high-performance applications,” said Polypore CEO Robert B Toth. “Together we are well positioned to meet future market demands and growth.”
