Samsung SDI to use Celgard separator in EV and storage system batteries

Celgard

The separator segment is sizzling – these critical battery components that keep anode and cathode from a disastrous meeting have been much in the news lately.

Polypore International (NYSE:PPO) announced this week that its Celgard subsidiary has entered into a long-term agreement to supply separators to Samsung SDI for its EV and energy storage system lithium-ion batteries.

Celgard’s battery separators are polypropylene (PP), polyethylene (PE), or trilayer PP/PE/PP electrolytic separator membranes.

“We are impressed with Samsung’s market position and the opportunities they have on both current and future vehicle models, as well as their demonstrated commitment to supplying global customer growth,” said Polypore CEO Robert B. Toth.

Separately, Polypore announced that it has filed a complaint against LG Chem, which it says infringed one of Celgard’s US battery separator patents. LG Chem recently lost a lawsuit with SK Innovation that involved battery separator patents.
