Celgard Enters into Exclusive Joint Development Agreement with Morrow for High Voltage Battery Separator Technology for LNMO Battery Cell Production at European Gigafactory

8 November 2022

Celgard, LLC, a subsidiary of Polypore International, LP, is pleased to announce that it has entered into a multi-year joint development agreement with Morrow Batteries AS ( Morrow). Celgard will work with Morrow to develop, test and commercialize next-generation dry battery separators for use in Morrow high-voltage battery cells, with lithium nickel manganese oxide (LNMO) cathode material, for electric vehicles (EV) and the energy storage system (ESS).
While separator development activities are already underway between the two companies, commercial production of Morrow's battery cells will begin at the Gigafactory at Eyde Energy Park in Arendal, Norway in 2024. Under the terms of the agreement , Morrow will exclusively use Celgard's proprietary dry membrane separators, developed under the agreement, in high-voltage batteries produced at its Gigafactory. Morrow has committed to undisclosed annual purchase volumes.

“For more than half a century, Celgard has been at the forefront of membrane technology. We are very pleased to partner with them to bring separators to market for Morrow's next generation high voltage batteries.

The partnership with Celgard provides a framework to accelerate the development of our LNMO-based products and is a big step towards Morrow's goal of being a global leader in cost and sustainability,” said Rahul Fotedar , chief technology officer of Morrow.

Additionally, Lie Shi, Global Head of Separator Business Development at Asahi Kasei and Executive Vice President of Polypore, added, “We are delighted to partner with Morrow to develop and introduce Celgard® membrane separators from generation for high-voltage battery cells manufactured at their Gigafactory, and we look forward to advancing electric vehicle technology with Morrow in Europe. »
