Meta Materials Granted Two New U.S. Patents for Next-Generation Battery Separators

Company Reaches Another Milestone with 410 Active Patent Documents

HALIFAX, NS / ACCESSWIRE / July 18, 2022 / Meta Materials Inc. (the "Company" or "META®") (NASDAQ: MMAT, FSE: MMAT), a developer of high-performance functional materials and nanocomposites, today announced that two new U.S. patents were recently granted directed to second and third generation nanoporous ceramic battery separators. Including new patent filings and the patent portfolio acquired with the Optodot asset acquisition, META now has 410 active patent documents, including 251 issued patents and 159 pending patent applications. META's patent portfolio comprises 98 patent families, of which 57 include at least one issued patent.

"These newly granted U.S. patents are directed to our second-generation NPORE® nanoporous ceramic separator, offering superior safety for lithium-ion batteries, and third generation NPORE® ECS (electrode coated separator), which is designed to reduce the cost of manufacturing while improving battery safety, lifetime, energy, and power density," said Dr. Steve Carlson, Executive Vice President, Advanced Materials and Battery Products at META. "Together, these unique products are designed to address the key challenges facing the electric vehicle industry."

US Patent No. 11,387,521, issued July 12, 2022, is directed to an advanced nanoporous separator for lithium-ion batteries which has far superior safety properties such as better heat conductivity and non-shrinkage compared to conventional separators currently used in lithium-ion batteries. US Patent No. 11,387,523, issued July 12, 2022, is directed to a new generation lithium-ion battery in which the cathode is directly coated onto the separator. This technology reduces the complexity and expense of the equipment used to fabricate the battery, for flat and prismatic batteries that can be used, for example, in electric vehicles. This US patent also enables alternative manufacturing processes, such as where a non-dried, wet cathode is applied to the separator.

"Since we reported Q2 2021 on August 12th last year, META's patent portfolio has grown by 175%, to 410 active patent documents versus 149, and we are now approaching 100 patent families, more than double compared to 46 last year," said Dr. Shann Kerner, META's Chief Intellectual Property Officer. "I am particularly pleased to see these two key U.S. patents directed to next-generation battery materials issue, providing META a sustainable competitive advantage in an important, new market segment."

According to Yano Research Institute Ltd., the global market for Lithium-ion battery separators was an estimated $5.1 billion in 2021 and is projected to reach $9.0 billion in 2025). SNE Research estimates that separator shipments were about 5.5 billion square meters in 2021 and are projected to reach 15.9 billion square meters in 2025. About 15 million m2 are required per GWh of battery capacity (10-20 million m2, depending on the battery configuration). For more on META's battery materials please click here or visit
