Celgard and Æsir Technologies Forge Strategic Alliance to Drive Industry Innovation in Nickel-Zinc, Zinc-Air and Lithium-Zinc Batteries
Celgard is pleased to announce a newly formed Alliance with Æsir Technology, Inc., a leading manufacturing company that specializes in developing next-generation Nickel-Zinc battery technology. This chemistry offers a stable cost-effective recyclable option with energy density in between lithium-ion and lead-acid batteries, making it an ideal choice for many applications. Together, Celgard and Æsir will collaborate on joint research projects to further develop high-technology next-generation Nickel-Zinc (Ni-Zn), Zinc-Air (Zn-Air) and Lithium-Zinc (Li-Zn) and Sodium-Zinc (Na-Zn) batteries used primarily in aviation, data centers, telecom, energy infrastructure and electric vehicle (EV) charging applications.
Celgard, LLC (Celgard), a subsidiary of Polypore International, LP, (Polypore) settled its litigations against Shenzhen Senior Technology Material Co. Ltd. (Senior China) and several United States defendants in the United States District Court for the Northern District of California and against Senior China in the United Kingdom (UK), and Senior China’s litigations against Celgard. The terms of the settlement are confidential. Celgard previously announced the successful outcome of the Targray, MTI and Farasis cases and will continue to protect its intellectual property (IP) regarding coated and uncoated separators for lithium-ion batteries and proprietary technology to safeguard its assets and customers.
Celgard is pleased to announce a major expansion at its Celgard manufacturing site in Charlotte, North Carolina. Asahi Kasei approved investment in Hipore™ wet-process coating and finishing lines at the site to meet the increasing demand for lithium-ion battery (LIB) separator in the electric vehicle (EV) market. Celgard manufactures dry-process membrane separator also used in vehicle electrification. The company already has a skilled employee base capable of applying technical coatings to base film shipped from Hipore™ sister locations and completing finishing steps required to meet customer specifications. With the expansion, the Celgard manufacturing site will be positioned to provide the best domestically sourced solutions to the market with a complete product portfolio. Construction will begin at the Charlotte site starting in early 2024 with operations planned to start up in 2026. The expansion will create about 100 new clean-energy jobs at the Charlotte facility.
Celgard Takes Another Step in Energy Storage Growth as It Forms Strategic Alliance with Lithion Battery for Next-generation Battery Cells
Celgard, LLC (Celgard), a subsidiary of Polypore International, LP (Polypore), is pleased to announce a newly formed strategic alliance with Lithion Battery, Inc. (Lithion), whereby the two companies will undertake joint development of battery separators for next generation lithium-ion cells with Lithium Iron Phosphate (LFP) cathode material. Through this collaborative effort, the companies will meet the ever-growing demand of supplying consistent power to those in need with energy storage systems (ESS) for uses such as micro-grid power applications. The cells could also be deployed in medical tools and military and industrial markets, where Celgard has been providing separator solutions for decades.

Celgard Enters into Strategic Alliance Agreement for LFP Battery Separator Technology with American Battery Factory
Celgard has entered into a strategic alliance agreement with American Battery Factory (ABF). Celgard and ABF will undertake joint research projects to commercialize state-of-the-art next generation products for reliable high-technology prismatic lithium iron phosphate (LFP) batteries in the U.S.
Celgard and Farasis entered into an agreement that settles the U.S. patent infringement litigation and the global disputes between the two companies. Celgard also added Senior-China back in as a defendant in Celgard’s California patent case and moved the North Carolina trade secret case back to the California court.
The necessary regulatory approvals are complete and the joint venture (JV) has been established between Polypore and Shanghai Energy New Materials Technology Co., Ltd. (SEMCORP) as Jiangxi Enpo New Materials Co., Ltd. in Gaoan City, Jiangxi Province, People's Republic of China.
Celgard Successful in UK Appeal Court, Keeping Injunction Against Senior UK Battery Separator Import
The Court of Appeal’s dismissal of Senior’s appeal supports the UK High Court’s Judgement in favor of Celgard, which not only granted the injunction against Senior, but also held that Celgard had established an arguable case that Senior had used its trade secrets in developing and manufacturing battery separators and that England was the proper forum for the importation dispute.
Celgard, LLC (Celgard), a subsidiary of Polypore International, LP (Polypore), recently filed an application for an urgent injunction against Shenzhen Senior Technology Material Co., Ltd. (Senior) in the High Court of Justice in London, England.
