Polypore to supply Celgard Li-ion battery separators to Panasonic

Celgard

Polypore International (NYSE:PPO) has announced that its Celgard subsidiary has entered into a five-year supply agreement with Panasonic under which the Japanese battery behemoth will purchase Celgard brand separators to be used in its large-format lithium-ion batteries.

Separators are critical components of a Li-ion battery, providing a barrier between the anode and the cathode while enabling the exchange of lithium ions from one side of the battery to the other. Polypore is a global filtration company specializing in microporous membranes. Its Celgard battery separators are polypropylene (PP), polyethylene (PE), or trilayer PP/PE/PP electrolytic separator membranes.

“After working closely together with Panasonic for many years, we are pleased to formalize our partnership with them. This agreement highlights the value of our capacity investments and our proven industry-leading products and technology, while providing certainty of supply to meet our customers’ needs in this growing application space,” said Polypore CEO Robert B. Toth. “Panasonic is a leader in battery technology and is well positioned to grow as new vehicle models continue to be introduced to the market.”
