The companies will work together to develop high-technology, next-generation nickel-zinc (Ni-Zn), zinc-air (Zn-Air), lithium-ainc (Li-Zn), and sodium-zinc (Na-Zn) batteries used primarily in aviation, energy infrastructure, and electric vehicle (EV) charging applications.
“Celgard looks forward to advancing next-generation Ni-Zn technology with Æsir that is critical to energy storage systems and powering communities by continuing to be at the center of membrane separator innovation,” said Stefan Reinartz, VP of lithium-ion EDV and ESS at Celgard.
Celgard will supply all of Æsir’s battery separators for current and future applications including a new battery factory planned for 2024. Celgard will also be positioned to offer separator products to future Ni-Zn and Li-Zn Æsir licensees or joint ventures.
“Celgard provides a special ‘Technology-Enabling’ separator that is integral to Æsir’s Ni-Zn performance, and we are excited to work closely with them to further drive innovation in our industry,” said Dave Wilkins, Æsir’s chairman and chief technology officer.
The company recently announced plans to expand its manufacturing site in Charlotte, North Carolina. An investment in Hipore wet-process coating and finishing lines at the site was approved to meet the rising demand for lithium-ion battery (LIB) separators in the electric vehicle (EV) market.
