CHARLOTTE, N.C., Nov. 7, 2022 /PRNewswire-ASIANet/ -

Celgard, LLC (Celgard), a subsidiary of Polypore International, LP, is pleased 
to announce it has entered into a multi-year joint development agreement with 
Morrow Batteries AS (Morrow). Celgard will work with Morrow to develop, test,

While separator development activities are already underway between the two 
companies, commercial production will begin at Morrow's battery cell 
Gigafactory at Eyde Energy Park in Arendal, Norway, in 2024. Under the terms of 
the agreement, Morrow will exclusively use Celgard's proprietary dry-process 
membrane separators, developed under the agreement, in high-voltage batteries 
produced at its Gigafactory. Morrow has committed to undisclosed annual 
purchase volumes.

"For over half a century Celgard has been at the forefront of membrane 
technology, we are very excited to join forces with them to commercialize 
separators for Morrow's next generation high-voltage batteries.

The partnership with Celgard provides a framework to speed up the development 
of our LNMO-based products and it 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, Asahi Kasei global head of separator business 
development and executive vice president of Polypore, added the following: "We 
are excited to partner with Morrow to develop and showcase Celgard(R) next 
generation membrane separators for high-voltage battery cells manufactured at 
their battery Gigafactory and we look forward to further advancing electric 
vehicle technology with Morrow in Europe."
